[Touche']

Yeah, this is really bugging me, too. I've been looking around, but I don't see any way to fix that yet.

EDIT: One thing that works, but is kind of a pain, is if you switch your phone into Landscape Mode from the tosay screen. Then, go into WMP and play your video...hit the 'full screen' button and it will play in landscape mode.

Like I said, it's kind of a lot to go through, but that's all I'm doing right now.
