Hi Diogo!

I don't know if this helps or not, but the mplayer-build of slackbuilds.org 
got a patch added recently for fixing xv with compiz.
The patch is for mplayer-1.0rc2 but it does also apply cleanly against trunk.
As I don't use compiz I can't test if it works though.
Here's the link to the patch:
