Hi,
I used DVD Decrypter to get .m2v and .ac3 files.
I got 2 files:
VTS_02_1 - 0xE0 - Video - MPEG-2 - 720x576 (PAL) - 4~3.M2V
VTS_02_1 - 0x84 - Audio - AC3 - 2ch - 48kHz - DELAY -80ms.AC3
The I went to TMPGEnc - MPEG Tools - Multiplex
Selected both files and produced one result.mpeg file.
My question is:
Did TMPGEnc handle the "DELAY -80ms" correctly?
How can I check it?
:confused:

simply play the resulting mpeg file in your software dvd player and see if the sound is in sync... if it would be off by 80 ms you would probably notice... if you can't notice it i wouldn't bother :P

If you did not tell TMPGEnc there was an 80ms delay, how is it supposed to know? DVD Decrypter puts it in the filename so that you as a user will know and perform the required steps to correct it on your own...
Killingspree is probably correct though, 8 hundredths of a second is likely unnoticable.

Hi, my first post here. I have also been very curious about the -DELAY flag in ripped audio streams. I've done several PAL -> NTSC conversions, wondering about the specific details of the flag.
For example, when slowing down a PAL 25fps to 23.xxx FPS I know the audio needs to be slowed down also, which I have done in BeSweet. BeSweet has a place to enter the delay. The resulting file "should" be in sync with the video stream.
However I also question the specific meaning of the -DELAY flag and how it needs to be handled when multiplexing. I have ghosted the forums for quite some time and never seen a specific description or set of instructions on how to use the -DELAY flag.
Any further comments by you experts will be appreciated.
