Loss of A/V Sync in VirtualDub

[TheEvilHammer]

I have several .mpeg files that play perfectly find in Media Player 7 without losing A/V sync. However, when I open them in VirtualDub and scroll to the end of the file, the sync is lost when the movie is played. This is odd because the sync is fine at the beginning of the file when played. Also, when the movie is encoded, the sync is fine at the beginning, but is lost at the end.

I have a temporary solution - open the file in TMPGEnc, and output the file to an .mpeg. However, this is a complete waste of time (2 hours for 22 minutes of MPEG video). Is there a setting or something I'm doing wrong in VirtualDub? Any help would be awesome. Thanks.

Any ideas?

Try clicking on Video -> Frame Rate and selecting "Change so video and audio durations match". This sometimes fixes a gradual audio drift.
