I have a GM945-based media centre PC that I just set up, although only
at standard definition. I also noticed tearing when playing full screen
videos with mplayer.

My solution was found by running "xvinfo", noticing that two X-Video
ports were ports were available and using the second.

For mplayer, this was a matter of running it with -vo xv:port=xx, where
xx was the port number of the second port. This can also go into
mplayer's config file.
