First step: set your Playback Profile group to Slim in mythfrontend
settings, Utilities/Setup|Setup|TV Settings|Playback, 3rd screen.
If that doesn't work, then I'd guess your video drivers are having
problems scaling the video (for example, as it might if you're using a
display size that's smaller than the video size--i.e. using ATSC
high-definition video on an 800x600 display).
