Edges chopped off when viewing burned DVD.

I asked this on the qdvdauthor user mailing list and it was suggested I
ask here, so...

I have some video I generated using Celestia.  I captured video as
640x480 OGG Theora at 29.97 fps,  then imported it into Kino.  After
editing, I exported as mpeg for qdvdauthor, then laid our my menus and
chaptere and burned a DVD.

If I play the VOB file with xine or mplayer, it looks fine.  mplayer
does tell me it is prescaling the video to 720x540 to get the 4:3 aspect
ratio correct (it *is* 4:3).

When I play back the DVD on my analog TV, I've lost part of the edges on
all four sides.  I can tell its missing because Celestia has text
displayed in those areas and its chopped off.

If I view it on a small portable DVD player, the left/right have a few
columns missing as some text on the edges is chopped.

But when I play it on a high-end upscaling DVD player on my 50-inch
plasma TV, the sides are fine, but the top and bottom are still missing
several lines.

dvdauthor.xml says the video is 720x480 4:3.  mplayer -identify says this:
