Recommended Video format for BGE?

I’m working on a flythrough that has a stadium and centerhung video display. the video size needs to be fairly accurate, and its large. I was wondering if anyone had found a compressed video format that BGE handles well.

I would suggest OGG or Xvid.

Yes, ogg seams to be used in the demos floating around and they have worked great for me.
