I know the topic of audio/video sync has been a running issue. I have tried the fixes listed.

I have a two hour program originally recorded on a VCR, and copied to a DVD with the VCR/DVD recorder. The DVD recorded on the VCR/DVD is listed by Windows Media Player as 2:02:04 in length, and is in perfect sync.

When I use EMC 8.0 Capture to bring that DVD onto my computer hard drive, the .avi video file is out of sync with the audio. I have tried using Capture to capture the sound separately. The .avi video file is 2:02:18 in length, while the .wav audio file is 2:02:11.

I also used EMC 7.5 Capture to bring that DVD onto my computer hard drive. EMC 7.5 captured the file as an mpeg, which was 2:02:11 - the same length as the .wav audio file captured by EMC 8.0. The EMC 7.5 file was in perfect sync.

It seems likely that the proper length of this file is, in fact, 2:02:11, but that for some reason the .avi file is some seven seconds longer than it should be. By the end of the clip, the file appears to be about seven seconds out of sync. The sound leads the video by that amount.

Any thoughts on why the .avi file would be longer than the same capture using mpeg or wav?

A 2 hour avi file? That must be a huge file since a 60 minute DV avi comes to about 14GB. Or is it some other avi format?

That's using the EMC 8 Capture default of "Standard Divx." The file extension is .avi. A two-hour capture is 1.68 GB.
