This is not a driver problem -- This is a userspace software issue.  Most
likely, the video is being shown to you at full size, and your screen resolution
is not large enough.  Mplayer (on my machine) will usually scale down the video
so that it fits on the screen, but this could also be related to your X video
card driver setup.

Try to hit 'F' in mplayer for "Fullscreen" mode, and see if that does anything.
 (depending on your video display hardware, it might not make any difference).

You may want to seek answers from the mplayer people on this one, or try a
different app.

Cheers,

Mike
