Having this issue too when I went to play a video on a large external monitor. Video playback works fine with "mirror" mode, but not otherwise.
Also, I just tried installing the new Lucid beta, and the problem persists. This is not totem specific, VLC and mplayer have the same issue. I'm not familiar with how video playback works, but it's obviously some underlying layer causing the problem.
