occured with playing video: mplayer -vo xv -ao sdl 
mplayer: MPlayer svn r34540 (Ubuntu), built with gcc-4.7 (C) 2000-2012 MPlayer
Team


later Crash in log:

- switch to 4th virtual desktop 
- open rdesktop program
- xorg is nonresponsive - try keyboard shortcuts to change desktop (dont work)
- wait until Xorg is restarted 

System:
-Linux Mint 15 (Ubuntu 13.04)
-NVAA (Geforce 8200) onboard (Jetway JNC62K)
-dual monitor setup

-Kernel 3.12-rc2

The attached dmesg contains several error messages that are missing from 68037
or are added compared to 69387.
It could be the same "bug"/"bugs" that are described in 68037.
Accel. Video often freeze, stability is increased when playing with x11(without
overlay) in vlc or mplayer. But that might be subjective.
