OK- so I learned how to demux audio track when in IFO mode and that's cool, but I noticed that in the generic name of AC3 track there aren't any values of delay like in SmartRipper (I am not a troll!) so I am forced to either use SmartRipper or leave both video and desired audio stream in Vob and then use Dvd2Avi demuxer.
Any other way?

Ermmm I think you need to look again. The delay is present in the file name and also in the info file created.
You are using the latest version - right? 3.1.6.0?

No Sir. This is the generic AC3 name I got when demuxing
VTS_01_1 - 0x80 - Audio - AC3 - 5ch - 48kHz - DRC - English.AC3

I am using 3.1.6.0...

Well I just ripped one for testing and I got this:

VTS_06_1 - 0x80 - Audio - AC3 - 2ch - 48kHz - DRC - English - DELAY 0ms.AC3

So either it wasnt possible to calculate the delay for that audio file, you quit the decryption process early or the file renaming function doesnt work on your operating system. What OS are you running?

Hmmm- it seems DD doesn't like some DVDs- the DVD I tried demux function on is The Best of Friends Vol4 - R1 .

It still doesn't rename file to include time delay but correct time delay can be found in StreamInfo file. Also it seems that every time it finishes demuxing that file it goes restarting my PC "the hard way". I can reproduce this error any time.

My system is Athlon 2000+, Asus A7V333, 512Mb DDR, DVD-ROM LiteOn HD-166S, WinXP+SP1. I never noticed this kind of behaviour but now that I tested a few more DVDs- it seems that when ending decrypting some of the DVDs DvdDecrypter tends to restart my PC. It usualy happens when using Demux function and on some DVDs only.

P.S.
Just talked to my friend who has pretty much simmilar PC configuration and he advised me that sometimes he experiences random restarts too. Is it possible that DD is calling some function that restarts system?

P.P.S.
OK- it seems I can definetly reproduce restart error on decrypting that DVD. On other DVDs it seems more or less random. In the mean time I also tried both ASPI and SPTI mode and experienced restarts all the same.

Is that just demuxing or does it always reset?
What if you demux video, but not audio?

I've never once in my whole entire life had that happen to me!

I will try to pin down precise environment in which this error occurr.

However- the good news is that on Akira R1 DVD delay times are correctly made into AC3 files names. However those Friends DVDs still refuse to produce correct names and after decrypting still restarts my system. I will try several combinations of demuxing and advise as soon as I narrow down what combination of factors is causing it.

I think I pinned down the problem causing restarts. As soon as I unmounted DeamonTools virtual drive restarts stopped. I don't know how is that related to restarts but I am pretty much sure it was the cause of my troubles. So far I haven't had a single restart. I must add that I haven't used DaemonTools to estract streams from DVD image but virtual drive was simply present in the system without even a image mounted on it.

As for the delay times not inserted into file names it seems that those Friends DVDs are tough cookies for DvdDecrypter and it still refuses to rename those files. Correct delay times can be founded in the StreamInformation file so I am using that fact to help myself.
With Akira however everything is working flawlessly and files are named with their respective delays.
