In addition to the MTRR range not set, there is no "OverlayMem"
specified by xorg.conf. This causes the multimedia player to close
unexpectedly when attempting to play a video file.

It also seems impossible to display a video larger than DVD resolution
regardless of the "OverlayMem" specified. The window must be downsized
to prevent a garbled display on a 960 x 540 video.

The CPU usage by the X server is still too high (15-20%) during video
play, even with the MTRR ranges set as above. By comparison, playing a
DVD video uses 70-90% CPU in Ubuntu, while the same video in Windows
2000 uses 40-60% utilizing DirectX.
