Regarding ati/radeon and the video not moving with the window when compiz is used, I have a workaround:
[I am using medibuntu's mplayer, I assume it will work with the normal one too. My xorg.conf is blank.]
Open video in mplayer, let it play, & stop the video - leave mplayer open. Open video in a new instance of mplayer: the video stays in its window when moved, all compiz effects (Alt-Tab, wobble, cube, etc.) work with the video staying inside its window. The original mplayer instance can be closed at any time after the second has started. [This might work in totem as well, but I do not know how to open multiple instances of totem.]
Once all instances of mplayer are closed, you have to re-do the workaround for it to work again.
