I found out more!  It's my laptop's fault.  Don't have a fix...
When I set my LCD to expand the picture to fill the whole screen, vo_xv
acts the way it's supposed to.  When I set my LCD to leave black space
around the unused portion of the screen, vo_xv does the strange cutting
off the picture thing.  And with vo_x11, it always does the right thing.

I'm stumped.  Anybody have any clues?  Why would xv do it wrong but x11
do it right?
