kwin compositing + mplayer VDPAU crash

Hello everyone, I have a very specific problem with KDE and mplayer video playback.
If I'm using vdpau as video output in mplayer and I switch to fullscreen mplayer will hang if anything is drawn on top of the video output. It happens if I show the control bar in smplayer or if I open yakuake or if I receive a skype notification.
There are three things that can prevent the crash:
- Using xv instead of vpdau (but 1080p playback becomes a pain)
- Disable "unredirect fullscreen windows" in kwin (but it kills the performances of games)
- Disable compositing before switching to fullscreen (that's what I'm currently doing, but it's annoying)
Is there a way to tell kwin to NOT unredirect only mplayer windows? Or any way to set up a specific rule to avoid the crashing?
Thanks a lot!

Re: kwin compositing + mplayer VDPAU crash

Mmmh... maybe you can deactivate compositing only for the mplayer window. I think you can do this by right click on the mplayer window frame -> advanced -> specific settings for this program -> go to the tab on the right (don't know whats the name in english, here in german the name is "Erscheinungsbild und Korrekturen", so maybe appearance and adjustments. And there is an option to block compositing. Maybe this helps.

Best regards!
