Running mythbuntu 10.04 and experience black screen/x lock up upon video playback, though ssh is operational.
Using kernel 2.6.32-21-generic results in symptoms reported but also has screen corruption when movement is present (mouse cursor, screensaver, or mythtv menu)
Using kernel 2.6.31-21-generic results in symptoms reported but there is no screen corruption with movement on screen.
