Ok Fellas just had a few buds again & The Debate went Sour Because we all didn't have the information, Plus we ran out of Bud. Gotta get another case. So while we are gone can someone answer these question. What are the Pros & Cons on DVD Recorder Chips, How do they stack up in Picture Quality? How do these Chips really stack up LSI, Zoran, Cirrus & In House Chips. Any Opinions?

.. honestly getting harder to keep track of this with new ones coming out ... the one thing I can say is none have toppled LSI .. many have stampeeded over Panasonic (once the only option, now thankfully that has changed)
... 4-6 are not far apart either. 1 is in league of it's own. 2-3 close too.
1- new DVD better than source, quality improved .. to date ONLY LSI does this
2-3- new DVD as good as source, quality maintained
4-5-6- new DVD, quality not at all maintained
I studied recorders first ... went back to find out what was under the hood. I was pleased that findings for recorders that looked alike were also ones using the same or similar chipsets!
... how the recorder implements these chips is anoth erthing to watch for also. Sony does a bad job compared to other ZORAN's. LiteON made a bad choice picking CVBR instead of VBR ... and I don't care what "banitc of LiteON" says about the "DVD+VR" spec being adhered too. Still a bad choice. Cyberhome is a piece of junk, makes bad chip worse. Panasonic has long choked on the failures of its own chips .. and by the time they were perfected, others can surpass their quality. Sorry, you lose Panny. Philips has never been much better, and the machines are a bit clumsy. Apex and JVC were the best quality I've ever seen, can easily outperform a Hauppauge and ATI card. But the APEX PSUs could blow up, not good.
The JVC DRM10SL has a sturdy machine, lots of features, and great quality, my #1 pick.

ALL TESTS are conducted in 3-4 hour time window. 6+ hour looks bad on most machines (only exception I've ever seen was a PAL Panasonic, still getting details on that unit). The 1-2 hour modes look the same on almost all units, though color loss sometimes still an issue on those 4-5-6 chips.

Cirrus chip enables universal DVD players
By Anthony Cataldo
EE Times
May 18, 1999 (3:57 PM EDT)
TOKYO — Japanese consumer electronics manufacturers plan to unveil "universal" DVD players with new audio features as a way to refresh their product lines and distinguish them from cheaper video players from other Asian competitors, according to officials at Cirrus Logic Inc., which has developed an audio decompression engine that targets the new class of players.
Several Japanese companies are in the process of incorporating DVD-Audio and other proprietary sound-enhancing algorithms and compression schemes into new players in the hope that early adopters will snap them up. Current DVD players do not support DVD-Audio, the hardware specification for which was not finalized by the DVD Forum until last February.
With the newer DVD players, Japanese consumer electronics OEMs will try to get a leg up on regional competitors selling Video CD players and shore up declining DVD prices, which have fallen as low as $250 in Japan. Officials from Cirrus Logic, one of the leading vendors of audio codecs, said they expect the first DVD players with the new features to hit store shelves by year's end.
"Many DVD makers gave up the low-end in the Far East because China, Taiwan and Korea are developing lower-priced players, like Video CD. So Japanese companies are planning to meet the higher end of the market," said Hidehiko Kondo, sales and marketing manager for Cirrus Logic K.K. (Tokyo).
Kondo said OEMs are looking to use Dolby AC-3, MPEG-2 and DTS DVD-Audio decompression standards in the new players. In addition, several vendors are also considering adding support for other sound-enhancing features such as High Definition Compatible Digital (HDCD), a proprietary algorithm developed by Pacific Microsonics Inc. (Berkeley, Calif.) that increases the dynamic range of CDs for clearer fidelity.
It is unlikely, however, that the first wave of universal DVD players will include Meridian Lossless Packing (MLP) audio since the standard is relatively new and there is still little software support, Kondo said.
Cirrus hopes to snatch a piece of the business for these new DVD systems by fielding its latest CS49300 device, which can decode PCM, MLP, AC-3, DTS and MPEG audio. And because the device is programmable, OEMs can include features such as HDCD, Dolby Virtual, surround field processing, bass/treble controls, bass boost and speaker delays. The chip is priced at $15 in 10,000-unit quantities. Samples are available now, and production is expected to begin in the third quarter.
When used in a universal DVD player, the chip receives data from a DVD drive control device and outputs to a set of stereo D/A converters. The chip also has a separate PCM/AC-3 output, and a can draw code from an external ROM containing code for standards such as MLP and HDCD.
The 0.24-micron device employs the same architecture as an earlier implementation for AVR systems. The architecture is made up of two DSPs, RAM data memory, ROM and RAM program memory and a phased-locked loop.
The 30-square-millimeter device comes in a 44-pin package. Crystal Semiconductor, Cirrus' wholly-owned subsidiary in Austin, Texas, will provide the decompression software.
Cirrus also plans to unveil two additional D/A converters and one new codec later this year aimed at DVD players. In the coming months, Cirrus will ship samples of two 24-bit D/As from its CS439X family which will target both mid-range and high-end systems. The mid-range device, which will be available in sample quantities in July, is capable of 196-kHz sampling frequency and has a dynamic range of 107 dB. Scheduled to be available in sample quantities in August, the high-performance version is a multi-bit architecture that has a sampling frequency of 196 kHz and a 120-dB dynamic range. Cirrus also plans to later include support for Super Audio CD, an extension to CD audio promulgated by Philips and Sony, in its high-end chip, said Terry Ritchie, vice president of consumer products for Cirrus Logic's Crystal division.
On the codec front, Cirrus will begin sampling by July its CS422X, a 24-bit codec that features 96-kHz sampling, stereo A/D, 6-channel D/A and volume control. All of Cirrus' planned D/A converters and codecs will be available in volume quantities three months after sampling begins, according to the company.

.. I'm sure I missed a few in the quick list ... my reviews on my site will be by brand (model variances discussed) and then chipsets will be listed, but with "confirmed" and "not yet confirmed" status. Not trying to mislead anybody, but this is not easy.
Have you tried to pry open on of these things? Normally you can't see anything, nothing at all. It's aggravating.
I have tested this one: Sharp DV-RW2U
People should use me as a "guide" ... a place to start ... verify and test on your own (as I would do listening to somebody else), and then report back errors as you find them (just don't be a dick about it is all I ask, we're all trying to help each other after all).Want my help?

There are facts and there are personal preferences/opinions, as long as you get the facts straight then people will respect your opinions. I won't waste my time on this issue and people can choose whatever they want to believe. -
Encoding chipset is only one of the critical factors in building a good DVD recorder, LSI Logic, Zoran, Cirrus Logic, Philips, etc. not only design DVD chipsets but they also sell the DVD recorder reference kit so the low cost manufacturers in Asia could assemble them cheaply. It's laughable to claim that X brand has a better product than Y brand simply because it used a LSI Logic chipset. Of course, it's just an opinion not a fact since it's rather subjective to compare PQ under different conditions such as the quality of monitor and souce materials used.
And I just love the following quote whenever I need a laugh:

What if the DVD recorders were cars?
- PANASONIC: 4-cylinder engine, fancy chrome wheels with neon lights and hydraulics (useless fancy junk). Early versions had floodlamps instead of headlights (IRE levels).
- APEX: V10 engine, tires a little low on pressure so beware of a blowout
- LITE-ON 5005: V10 engine, tires fine, body decent. The 5001 forgot to put in oil or ventilation.
- JVC: V10 engine, but steering wheel is on the right side
- PIONEER: V8 engine, drives great, expensive. Has SUV models too.
- SONY: V8 engine, drives great, expensive.
- TOSHIBA: V8 engine, SUV but back doors won't open
- SHARP: V8 engine, square wheels
- CYBERHOME: V6 engine, tires fell off while leaving lot
- MUSTEK: V6 engine, square wheels
- POLAROID: engine still unknown, hood was welded shut and the wheels fell off while leaving lotOriginally Posted by lordsmurf -
kcfoulk,
I have LIteOn 5001, JVC DR-M10S. I had Pioneer 220s for 2 days and then Pioneer 210s for another 2 days of intensive testing. And I can tell you for sure: Pioneer quality is worse than LiteOn or JVC, even at XP (one hour mode)
And LSI Logic rules.
I've never tried any Panasonic and will never will becasue when I was encoding everything on PC, I tried Panasonic MPEG-1, and then MPEG-2 software encoder. MPEG-1 for VCD was ok, but MPEG-2 software encoder quality was not good compare to others that I tried: TMPGEnc, LSX, CCE, MC, MPEG.Now. -

Think about it. it might have been a small team of one or five people programming that software. That does not stand for the home company. I did not like the Panasonic VCD encode two but i love my 27 inch Panny flat screen. I love my eight year old $900.00 dollar VCR that has one of the best picture with noise reduction. Every company make good and bad. The only company I do not like is Sony. There burners are junk DVD player's break down more then other brand's there a law suit out in LA about this. PS2 die all the time. But they make good Flat screen TV. But they still cut corner's with feature's. But there made well i'll give them that but would not buy another one.

When you open a lot of these recorders, what you see is "stuff" ... the motherboards are buried underneath eveything else. Some of them have heatsinks on the chips too, so I don't dare pry too much off, especially when I intend to take it back. A few also had warranty seals, don't dare open those either (must rely on info online).
The Samsung unit I had was not a rebadged Panasonic. Those are easy to spot ... they look like Panasonics. This one did not. Which model? Didn't pay that close attention at the time. Remember, I do this for myself.
Synergy, kcfoulk ... like I said, I share what I know. Your condescending attitudes are not desired. You are useless the way you act. If your reviews differ that is fine. That is fair. If you have new info to add to the ever-changing scope of DVD recorders, tell everybody. It's good to share. If you just want to come up here and belittle people to make yourselves feel better, **** off. Trolls are not needed on this site.Want my help? Ask here! (not via PM!)

I have Daytek P-30 (LiteON LVW5001) and Philips DVR75. Both recorded nicely and I feel the recorded disc PQ is slightly better (soften blurred pictures and brighter with increased contrast) than the original. Pricewise, Philips is selling $389.99 at Costco Canada whereas Daytek is selling $349.99 at Future Shop.
I am not an expert I am a general consumer. To me the PQ are both good on my 32" TV. Daytek is a lot easier to use. Philips has more editing capabilities, features and more inputs and outputs. Maybe the rest of the DVD recorders are just the same to me, general consumers.Sam Ontario -
LordSmurf and Synergy both contributed valuable information on DVD Recorders and Chipsets. There is no need to get excited. Cosumers like me, thank you all for the contributions.

All the original poster wanted was anyone's opinions not bashing. Lordmurf's chipset ranking was solely his opinion and it should have been left alone. Anyone who did not agree should have made their own ranking.
I question the credibility and motive's of someone attacking other people on this board.
I have tried several Standalone DVD recorders. Whatever chipsets they use, this is what I thought as far as quality.
1.JVC - DR-MV1S
2.Sony - RDR-GX7
3.Philips - DVDR-75
4.Sansui - DVD/VCR combo
5.Panasonic - DMR-E60
6.Cyberhome - CH-DVR1500 -

It's clear that Zoran's Activa 100 (the MPEG-2 encoding chipset) has never been used in any of the above mentioned models. So much ado turns out to be nothing.

kfoulk, you're missing the point.
I tested recorders for myself. I wanted to buy a good one. I refuse to pray to the "Panasonic god" like others, as it is unwarranted from it's mediocre-at-best quality, so it that regard, I'll always pick a fight (you found a perfect link with those exact words "pick a fight").
In my travels, I saw lots of recorders. I thus shared what I saw. Remember, I don't get paid for this, so I just do what I can and what I want.
In the studies, I noticed trends. I have attempted as best I can to ID the chips (the "under the hood" stuff). This is not easy info to come by, rather it be online or hacking apart the box.
If some info on chips I found is wrong, so be it. I'll update the list. But rather than nitpick at what's wrong, why don't you ******* make yourself useful and find the correct info? If you don't like my quality rankings, then make your own. Troll.Want my help? Ask here! (not via PM!)

I appreciate the insight, experience, and advice that you ALL offer, in the various discussion boards on this site.
I agree with the statement that "condescending attitudes are not desired". However, I don't agree with the statement to "f... off".
Let's keep the focus on the subject of the topic. And, avoid a focus of "my opinion is better than...". Ego's are a polluting factor in a forum for learning.
Again, I appreciate and respect all of your opinions. You all have taught me a great deal. Differing opinions are healthy for growth.
When presenting an opinion that differs from someone elses, pay no attention to that. Merely offer your experienced perspective on the subject. It's a great opportunity to broaden perspectives and sharpen understanding!
Thank you all, for you participation and contributions on this site. They are all valuable. And, I hope that you ALL continue to participate. As, I'm certain many others hope for the same.
Hope to see your continued posts. -
