Aspect ratio in VDub

[AngusMacGyver]

Hello!
I have a doubt. Does VirtualDub care with aspect ratio of a avi?
When I use resize, aspect ratio changes in avi, but TMPGEnc "knows" (i dont' know how) the original aspect ratio of a avi.
When I try to change a avi from widescreen to fullscreen, it's better to use "No Margin" in TMPEnc. But sometimes, I do vcds with subtitles using a filter in VDub. So, I can't use "No Margin" in TMPEnc because it will cutoff part of subtitles.
