    A. You could measure it. But it would either be 16:9 or 4:3 and I would be guessing 4:3.

    B. DivX and Xvid are MPEG-4 which allows a flag to set the Aspect Ratio. It works irrespective of container to (you didn't mention a container (Xvid is just a video codec))

    Fact is though that your problem is probably due to overscan and not all players support ARS (Aspect Ratio Signalling), so even if you changed the PAR (Pixel Aspect Ratio) the player may just assume 1:1 anyway so there would be no change.

    Does the picture actually look distorted?

    Better to use say FitCD to do the calculations and create an AVISynth script to encode. That way you aren't converting to RGB24 and back. Does mean that you would have to process the audio separately, although there was a DSynth mod that would allow you to directstream the audio whilst modifying the video.
