Laptop with ATI Radeon X200M, 2. Desktop system with ATI Radeon HD6450). Media players doesn't report dropped frames, CPU usage is well below 100%. Tested with a 720p x264 video at about ~6000kbps. See https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video- ati/+bug/961124. Tried Fedora 16 and the problem is the same.

I also noticed that if I run glxgears (Vsync on) I can see stuttering there too, but not that often (every 5-10 sec).

Which version of gnome-shell are you running? Have you configured compiz and kwin to unredirect fullscreen windows?

Also if I try to play an SD Xvid (632x486) video it's smooth even on fullscreen. This indicates that the problem depends on video resolution. I tried turning on the unredirect fullscreen windows option, but it didn't help. I have Gnome Shell 3.3.92 and 3.2 (in Fedora).

The interesting thing is that the 1280x720 video is running smoothly at 600x400.

Cause mplayer isn't complaining about dropped frames the best explanation is that instead of a constant stream of frames: ---*---*---*---*---*---*---*---*---*--- ... We get something like this: ---***---------****------------*---*--- ... That is usually caused by to long pipelines, e.g. the 3D rendering causes to long stalls, witch lead to burst of frames with the playback... I'm also guessing that you are using Xv + "classic" mplayer, could you try the VDPAU implementation with mplayer2 instead? The result won't be better, but you get at least a good error message of what is going wrong here.

I'm already using Mplayer2, but with XV - Textured Video. If I try VDPAU I get this message: "Failed to open VDPAU backend libvdpau_r300.so: cannot open shared object file: No such file or directory".

The glxgears FPS should be at 60 all the time. If I run glxgears during an SD video, it starts stuttering and tearing.
