Trouble after converting an avi to mpeg..

[Spektral]

Hi. I'm having some trouble with an avi file I downloaded. I ran it through TMPGEnc, and it converted just fine. However, once I burnt it to VCD, and popped it into my DVD to play, I noticed something was very wrong. The video is nice, crisp, and clean.. and the audio syncs, so everything seems to be fine.. except that it is disproportionate, and cutting off some of the picture around the edges. I'm sure there's a term for that, but I'm new to this and this forum, so please, be nice.

Anyways, I followed the guides on this very helpful site very carefully, and have tried doing this 3 different ways now, each time has produced the same results. Any thoughts/ideas? If you need more information to answer my question, just ask, and I will answer as best I can. Thanks in advance.

And do a forum search for overscan about why it is cutting the edges.
