Audio Sync Issue

[mjp14]

About 1 out of 15 DVDs I convert to XVID the audio (5.1) is out of sync by about 1/2 second. What is the best way to fix this? Also, one movie plays and double speed for some reason. Is there a way to fix that also?

Hi!About 1 out of 15 DVDs I convert to XVID the audio (5.1) is out of sync by about 1/2 second. What is the best way to fix this?

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
