adjust the sorce rate so that the video and audio durations?

[klumbz]

I'm converting some 20 minute episodes of an animated tv show.
I'm converting from .rm to .avi, then process some filers to smooth out the 2d images in vdub, then convert to vcd mpeg and burn.
About halfway through the 20 minute clip the video starts to slowly move ahead of the audio (I'm thinking this is from all the converting some frames get dropped).
So anyway, I was reading here that I can adjust the sorce rate so that the video and audio durations match using vdub (video > framrate) and that process totally got the clip in sync.
these clips average 15-38fps.
But doing this makes the video clip look much worse than if i had'nt.
anyone have any tweeks in this settling that could maybe help?
Or explain what im doing wrong (or at least what I'm doing. )
thx
