i was wondering the same thing. Found the movie in the place mentioned, it's called framwork_345345_blahblah.wvm
I can play the opening "20 the century fox" part in any media player then it hangs. However, Gallery can play it fine. I am going to try and move it out and put it in my movies dir and see if gallery sees it .. nope, it will play from that directory if I use Gallery as the player, but the Gallery up doesn't show it as a movie in my movies list. Wonder if I play with the extension...
Edi: nope, even changing the extension to mp4 didn't work. Unless gallery didn't refresh or something.
