Binary package hint: pm-utils

Video playing works greatly untill the laptop first time suspends to RAM. After resume everything seems ok, but playing video is slow, choppy, unusable. It concerns all kinds of high resolution videos, for example either with flash pluggins in FF or mplayer x264 1280x720.  It does on multiple player softwares like totem, smplayer etc.
 Also it is not compiz related, the same behaviour observed without effect on metacity.

I suspect a script for suspend to do something incorrect with video
system.

Release:	11.04
 2.6.38-8-generic-pae #42-Ubuntu SMP Mon Apr 11 05:17:09 UTC 2011 i686 i686 i386 GNU/Linux
pm-utils:   1.4.1-7

logs from mplayer,lshw,pm-suspend.log included
