JVC DRMV1 sound sync problem

[stimpy1864]

Ok I've been reading all the glowing reviews of the new JVCs. I work in a store that sells JVC Toshiba and Panasonic I personally own a Pana DRME30 and am thinking of upgrading. I brought in a concert VHS I have transferred with my pana before set the JVC to FR 90min for best quality in VHS to DVD-R dubbing mode. After work I compared the DVD from the JVC with the one I did on my pana and the picture looked the same (just about as good as a VHS dub can) but the sound on the JVC recorded disc was WAY off about a full second! The playback unit was a Pana RP-82 one of the best reviewed players out there and I've never experienced sound sync problems with this unit. So far of all the new DVD recorders we have got in I am most impressed with the Pana DMRE85 on screen VCR plus TV guide and a 120GB hard drive (a timer programmer’s dream machine) or the Toshiba RDXS32 with tons of options for tweaking sound and picture settings. I’ve done some recording with the Toshiba and have been impressed. I especially liked being able to turn up the bit rate for the dolby sound I could hear the difference and oh ya the picture and sound stayed in sync. The one unit I am ruling out is the JVC.

Clearly you have no idea what you are talking about as the Toshiba has the "black level" bug and is to be avoided therefore at all costs!

I wouldn't use it if I got one for free!

Also there is no way on green earth you can hear the difference between say 256kbps 2.0 AC-3 and 448kbps 2.0 AC-3 so again you are full of it.

P.S.
The Panasonic DMR-E30 also has the black level bug :P

Yes I do hear the differance in the AC-3 settings and as far as this "black level bug" I always use a video processer to adjust my levels while monitoring the results with a recording RAM disc. VHS tapes always need some tweeking anyway. I don't know if anyone has tested the new Toshibas for it's black level but the one disc I recorded looked fine. As far as the JVC goes I would much rather have this so called black level bug than sound with a one second delay. But why would you want to listen to someone who can test all the major brands side by side because I guess everyone opinion but your own is just "full of it"

[FulciLives]

Because I've "been around the block" as the saying goes and read alot.

Nothing you say seems to "match" the facts of the equipment you are using or basic sense facts like the human ear not really being able to hear a difference between 256 2.0 AC-3 and 448 2.0 AC-3

As for the JVC screwing up no device is perfect. I assume it was probably a fluke possibly due to a bad disc or cheap media. You can't dismiss a device for one bad "slip-up".

Also it makes absolutely no sense to use a Panny DVD-R(AM) as a source to record to the JVC. Of course it can't look any better as the Panny already did the damage.

Take a VHS video and using the exact same VCR make one copy to a Panny and one copy to the JVC and the JVC should kick ass.

The only thing the JVC seems "poor" at is VRO mode on DVD-RW and DVD-RAM but DVD-R looks INCREDIBLE as does DVD-RW in DVD Video mode (not VRO mode). With DVD-RW in DVD Video mode there is really no real need for DVD-RAM anymore.

Take a look see at this here thread:

It has been confirmed that the Toshiba unit you mentioned has the black level bug. It's all over the avs forum website.

I don't think you understood my last post I did record from a VHS directly on the JVC and compaired it with one I recorded on my Pana. I was using a Maxell DVD-R disc. I recorded another disc today the exact same way as yesterday and this one did not have a sound sync problem. I have recorded hundreds of times on my Pana and never had such a obvious sound sync problem. Maybe it was just a freak thing but none the less it made a bad first impression.

.... After work I compared the DVD from the JVC with the one I did on my pana and the picture looked the same .... but the sound on the JVC recorded disc was WAY off about a full second!. The one unit I am ruling out is the JVC.

I already recorded 12 DVDs using JVC DR-M10SL and I did not have any sound synchronization problems. I was also using Maxell DVD-R.
I also Panasonic DMR-E60 owner and there is no way the PQ of Panny is the same as JVC. JVC is much more superior. IMHO of course!

Must have been. I've made over a dozen transfers with my JVC, in various modes, and no sound sync problems whatsoever. Several of them were from old VHS & Beta tapes circa the mid-eighties. If it happens again, let us know.

I know this may not be a popular view point but I also have experience some sort of audio sync problem using my JVC M10. I thought it was a software problem because I copied it to my computer for editing.

I only had the machine 2 days now and I'm testing it every minute that I can. I own the Pana E30 and E50 and never experienced any sort of sync problem. In one small area of the video the sync was off about a sec. Then about 5 minutes later the sync was good again.

I don't want to jump to conclusions beacause I am still testing the machine and it's too early to render a conclusion. All I know is the quality beats the Pana in every way.

After futher testing, I found the sync problem had nothing to do with the JVC recorder, but the Ulead DVD Workshop program. What was happening was because the JVC uses 384 kbps Dolby digital and DVD Workshop uses 256 kbps, the program would render the audio portion of the video thus creating a sync problem.

I had to create a profile that has the settings equal to the JVC and now there is no outside rendering neccessary.

Ah-ha! That's a nice program, though. Personally, I've just been using TMPG DVD Author.

I have sound sync errors if the INTERVIDEO AUDIO DECODER is audio decoder in use. All you WinDVD fans ... ditch it. CYBERLINK is much better as far as the JVC is concerned.
