i made a DivX avi TV capture (yes i know there are better formats to capture too)
I used 44hz 16bit mono pcm sound
it recorded fine and the sync is good i edited out some adverts using virtualdub
when i convert the audio to mp3 the last 1/3 of capture audio goes a little out of sync only by half a second
with the same edits i made a direct copy(vdub) so the sound stayed pcm
i had no sync probs with this but again when i mp3 tha audio of this file the last 1/3 goes out of sync

any ideas whast happening n how i can fix it?
Thanx ahead
