The old version of News at Seven used procedural materials (512x512 IIRC) to play movies, and that seemed to run ok. It was a small map with not much going on, but it was also just running on my non-beefy laptop, and I definitely did not know what I was doing. Here's a link to the Wiki with code we used for playing movies: http://developer.valvesoftware.com/wiki/Avi_materials
