I've discovered another workaround, but it too requires a tradeoff. If you install the xserver-xgl package, video playback seems to work fine, and it also enables the water effects compiz plugin. However, I hear xgl is slower on intel than aixgl, and it will crash if you attempt to run any other direct rendering 3d program. So I guess we have to choose - 3d graphics or regular video.
