LiteOn Ripping Speed, Normal?

[pelsamra]

I have a LiteOn 16X DVD-ROM for rippping. When using DVD Shrink it says that I'm ripping at approx. 3000 KB/s to 4500 KB/s. Should I not be ripping at 16000 KB/s as I have a liteOn 16X DVD-ROM? Or do I have this completly wrong.

Thanks

"Or do I have this completly wrong. " Short and sweet. Yes and everything is fine.

[pelsamra]

Why is that? Can you please give me more info.

Thanks

The ripping speed depends on a number of factors. Your PC setup (i.e. processor speed, RAM, HD fragmentation, etc.) has a lot to do with it. The other thing is the transfer mode of your DVD-ROM. The transfer mode should be DMA, not PIO. Another factor is going to be the software you use for ripping and the level of compression needed to fit the movie on a 4.3Gb disk. The more compression, the longer it will take to rip.

Actually 4,500 KB/s isn't bad. How long does it take to:

1) Rip a DVD with compression?
2) Rip a DVD without compression?

In my setup, DVD's requiring no comression can take as little as 5 minutes. DVD's requiring compression usually take no longer than 45 minutes. Check your times to use as a benchmark, then tweak your system, software, etc. to see if you can improve on those times.

I also find that every movie will rip at a different speed. Some will transfer slower then others.

And some firmwares have limited ripping speed, which is supported to make it harder to make illegal movie copies

Of course, this artificial barrier is meant to be broken, with the help of tweaked firmware (which is usually region free also)

First and foremost, it is because 16X is the maximum possible achievable ripping speed, given perfect conditions (in a vacuum), on the very outer edges of the disc. In reality, if you average between 5X and 10X you are doing exceptionally well.

It is a fact that CDs and DVDs are read quickest when the very outer edges are being read, whereas they are read slowest at the very inner edges. It's not constant all the way through!

When you consider that the data goes from your DVD Drive, down the IDE cable, through your RAM, back up the other IDE cable and onto the Hard Drive, it is no surprise that there are losses and that your true ripping speed is lower than the perfect value.

You are obviously using a transcoder.

With dedicated ripping software such as DVDDecrypter or Smartripper, the ripping times will not fluctuate anywhere near as much as the values you have stated.

I have a Lite-On HD-166S with modified firmware with the rip locks removed and is RPC-1 it will rip a sigle layer at 14x and dual layer up to 10x.These drives are locked to around 6x from the factory.

What is the filmware update on this liteon 163, I just bought this at walmart and was wondering if I need to update the filmware. and how can I test the rip speed?

Thanks for your information. I have been contemplation upgrading from a no name DVD that seems to rip at 6X and the info on the Lite-On is just what I needed to make the decision.

I found that 12x or 16x they all rip dvds at just about the same speed.
Locked drives DL disc are 2x
Unlocked drives DL disc are 6x to 10x
Unlocked drives silver disc are 12x to 14x
Unlocked drives dye disc are 6x to 10x

Pioneer drives seem to read damaged disc better, but of course it throttles down

Lite-on is not bad on damaged disc and is very fast from begining to end.

LG is slow to start up but speeds up really quick, funny thing is that LG reads disc that Lite-on won't read, ( a batch of crappy data princo disc).

Hope this helps :P

I have unlocked my Lite-on with the 12x firmware from Codeguys... a while ago, in fact. Well before I read this thread.

It still takes 15+ minutes to rip a dual-layer DVD. Not too bad, but certainly not lightning fast. It starts around 5x and ramps up from there, peaking around 10x.

And before you start, my machine is ABOUT as fast as they get right now, and perfectly tweaked.

P.S. It's interesting, because I remember before I even got a burner, that my Hitachi GD-8500 used to rip with CladDVD ( http://www.clonead.co.uk ) a dual-layer in about 7 minutes. Hmm...
