If you want to be able to tell for sure what kind of frame it is you should use one of the variations on VirtualDub like VirtualDubMod to read the VOB files directly. Not only will it allow you to step through one frame at a time, but you can find the keyframes (I frames), which will then allow you to figure out what type of frame each subsequent frame is. All you have to remember is that the pattern is IBBPBBPBBPBB. It's possible that it repeats a little longer than that, but I've never seen a professionally authored DVD with a GOP longer than 12 frames.

Thanks. I've really gotten quite interested in this since moving up to RB-CCE, and if there are any other tools you could recommend (?), I'd appreciate it.

My post crossed yours in cyberspace. While it may be difficult to take the author seriously, I think that "objective" data is a step in the right direction.
I definitely agree that it's a good start, but as I've made clear in the past I'm a very critical judge of methods when it comes to these types of tests. This one is better than many I've seen, and I'll be watching to see whatever else comes out of it. I definitely agree, however, that this test shouldn't be discounted out of hand any more than it should be blindly believed. Since he said he's still testing I'll certainly be looking at his future tests before passing any real judgement. On the other hand it doesn't make a huge difference to me either way since I don't use anything besides CCE for compressing movies. I only use Shrink on menus, and only then to try to keep them under 100MB (about 2% of a blank).

Good point? It effectively reduces portions of the test to an opinion.

I'd agree that the test by itself becomes more of an opinion, or more accurately is only accurate if that assumption is true, but that doesn't mean it can't be useful when grouped with other tests. It's not a good standalone test, but since he says he's doing more I reserve judgement until I see how those are done and what results he gets.

Honestly most of the tools I have are oriented towards doing manual re-encodes with CCE. My favorite additional tool is called MPEG Stream Eye (aka MPEG Stream Explorer) by Elecard. It can open an MPEG file (including VOBs) and tell you a lot of information about the bitrate. It can also show you the order that frames are decoded in which is very instructional in understanding how MPEG compression works. I got a trial version several months ago, but it appears that it's in their developer's section now. PM me with your email address and I can send it to you.

Thanks. Sent the PM. Also, if you have a tool that can increase the audio (gain?) with CCE I would sure appreciate knowing about it.

The first problem there is that DVD-RB doesn't do any processing on the audio. It just demuxes and remuxes it. The next problem is that on AC3 and DTS tracks you need to start by decompressing them into individual mono WAV files, boost the gain, and then encode them again. Besides the fact that it's difficult and time consuming, it's also expensive because a "real" encoder (at least one that handles more than 2 channels) ranges from kind of expensive to incredibly expensive.
If you get past those obstacles there should be many programs that can do it. There's a free program called Audacity that I used to use for that on my TV captures, and with all the good things I've seen about Goldwave I'm betting it could do it as well.

Thanks for the explanation. 'Sounds like an amplifier and speakers would be the way to go for right now.

About the test. I hope the author gets it cleaned up. I do find it fascinating that he jumped into a group of true believers and said that just maybe "the king has no clothes."
Personally, I'm concerned about all the 3.2 hype being accepted as fact by folks with open arms. If you have something good to say, no one challenges it. Talk about the virtues of another transcoder, and your asked to prove it. I've been to two forums where, if you likely said you had a problem with Shrink, you'd be ostracised.
I think I've even witnessed a move to import this Shrinkmania to AD. I hope it fails.

You should have been around in early June when this thread first started, or just go back and read some of the early posts. The "Shrinkites" are already here and have been for some time. You've been shielded from it because they don't know enough to argue it over CCE.

Sophocles, Amen to that brother!
At least when we agree to disagree about the merits of an application we have tried it and used it and have actually seen results without taking somebody's word as gospel.
Reminds me of lemmings in a mindless dash towards the cliff's precipise...

Am I to understand that the DVD Burner itself does NOT play a role in quality?
I have the Sony DRU 700A (I think that's the model #). Is this an inferior burner to something else?

Sophocles ... I have come across some of that, but I thought that it had died down. I should probably brace myself for another attack...and try not to get sucked in.
Hi Big-O. I was hoping you'd get caught up and join this thread. I like your lemmings analogy. This Shrinkmania thing does seem a little mindless to me. Hype upon hype.

Hi Dr_John...
There's actually an AD forum where you could get a wealth of info on your drive. It is DVD+/-R Drives under the PC Hardware orange bar on the Forum's front page.

I should have added that I don't know much about your drive. Sony does make a good product, and if all your software is installed correctly, it should work fine for you. The actual quality of the backup is a function of the transcoder software used. Be sure to check into any firmware updates, though. This link will take you directly to the 700A page. http://sony.storagesupport.com/dvdrw/dru700adwn.htm
I should also mention that I am experiencing a time-lag with posting today, and it may have looked like I was ignoring your question. 'Sorry about that.

hello partners! what's up Nephilim?
here is a hard one for you guys...
A guy running XP HOME EDITION burns movies in about 15 to 19 min using shrink and Decrypter.
The same guy decided to upgrade to XP Professional and now the movies take TWO HOURS to burn
WHAT WENT WRONG?
Even the TECHS at BestBuy couldn't figure it out?

He probably needs to reset his DMA settings in device manager. Go to device manager and look for IDE/Atapi channels,go to the primary and secondary channels and right click on them, then to avanced settings. Another strong possibility, he needs to reinstall ASPI drivers. I'm betting that it's his DMA settings that is causing the problem.

Thanks partner!!! how do I rest the ASPI driver?
On the device manager,it says DMA IF AVAILABLE, it is that what tou are talking about?
Let me know.

Flanker,
If you have Nero installed, go to InfoTools. If not, dl it from here. http://www.nero.com/en/631940826989307.html .
Under ASPI you should have an "installed properly" green bar for system ASPI, and one for Nero (if it is installed). Under Configuration all your drives should show DMA on. Also, make sure your HD is defragged.
