Are you sure the video isn't encoded with black bars? ie if it is,
say, a cinematic ratio of 2.35:1 someone may have encoded it to 16:9
by adding bars to top and bottom?

Also the file may have its own idea of what its aspect ratio should
be. What does the output of mplayer say about it? Theres usually a
line or two that says what it is scaling from an to.

The best way to see mplayer's output is to ssh in to the myth machine
from your laptop as the same user as runs mythfrontend then do:

export DISPLAY=:0
mplayer ... etc
