I have a DVD with just one music video on it that I want to convert to xvid. I normallly use DVD Decrypter to extract and demux the vob and I get the audio delay information. But this time DVD Decrypter says it is not a DVD? So I can't use it.

So I use the latest version of DGIndex to get the demuxed audio track but there is no audio delay information. I tried muxing that with the converted xvid video and it seems to be off sync.

How else can I get the audio delay information? Or do I have to just try different values until I get it right? Thanks.

Load the file into VirtualDub, VirtualDubMod, or NanDub.
Set BOTH "Video"(VirtualDub, VirtualDubMod and NanDub) and "Audio"
(VirtualDub and NanDub - VirtualDubMOD>"Streams>"Stream list") to "Direct Stream Copy".

A) If the difference between audio and video is constant throughout the

video:

From the "Audio" dropdown menu, select "Interleaving" (For

VirtualDubMOD, rightclick on the listed audiostream and then select

"Interleaving")
Under "Audio skew correction", set an appropriate number of

milliseconds (positive or negative) in the box labelled "Delay audio track

by"
Save with a new filename


B) If the difference increases as the movie plays:

From under the "Video" dropdown menu, select "Framerate" - and

select "Change so video and audio durations match"
Save with a new filename
