I don't think that's the problem. The X desktop and the Myth UI both look
correct. Neither of them is getting 10-15% of the picture chopped off on the
right side. I only see the problem during 16:9 video playback. I have Myth
configured to use the same video mode for the GUI and for playback, so it
isn't that either.
