Since I have compiz running, I can't scale videos in mplayer anymore. Some slight scaling up to ~120% is possible, but some few % too much and the framerate immediately drops to almost nothing. I use the gl2 output. Without compiz same videos remain scalable. I don't know whether its compiz or mplayer or the combination of it. Reproducible: Always Steps to Reproduce: 1. have compiz running 2. start mplayer with gl2 video output 3. go to fullscreen / scale window Actual Results: framerate drops < 1 fps Expected Results: smooth video decoding mplayer/compiz use flags: [ebuild R ] media-video/mplayer-1.0_rc2_p28058-r1 USE="3dnow 3dnowext X a52 aac alsa arts ass dts dvd encode gif gtk iconv jpeg mad mmx mmxext mp3

Expletives won't help.
What if you use another vo?
I'm not a compiz user, though there has been some talk about it on the nvidia forums. Seems you need to use some Nvidia/OpenGL/Compiz specific VBlank Syncing settings, described at: http://www.nvnews.net/vbulletin/showpost.php?p=1724807&postcount=16 referenced by http://www.nvnews.net/vbulletin/showpost.php?p=1914816&postcount=6. Could you try those out, test a bit around, see if it helps?

Tried it out and it actually did help. Thanks for pointing me in the right direction. Following the steps on the referenced page I simply added "nvidia-settings -l" to my compiz startup script and now it works with gl and gl2 output drivers.
