When playing back video files it seems that my screen is divided into four quadrants.
In the top left quadrant the video appears to be playing normally.
In the top right quadrant the video seems to be a horizontal smear of the video.
In the lower left and right quadrants the video seems to be a vertical smear of the full screen video.
I am running the video card (ATI (Dell) X300, 128 MB) at 1920 x 1200 resolution.
I have tried to step the video resolution down to 1024 x 768 in both Ubuntu (8.04) and also in Boxee, which seems to follow the Ubuntu screen resolution settings.
