 I'm using an Nvidia GeForce 9400GT on a AMD64 X2 4200+ cpu.
 I created a video profile to use VDPAU accelerated playback for anything
 that has a higher or equal resolution of 1280x720.

 The problem I see now is stuttering of the video, a log with -v
 playback,important,general (on the frontend) output lots of these
 messages:

 {{{
 NVP(0): prebuffering pause
 }}}

 This happens on BBC HD, ZDF HD, HD suisse and arte HD. The 720p channels
 (all except BBC HD) are OK after a few minutes, BBC HD isn't recovering.

 I tried to enable OpenGL vsync, disabled real time priority, disabled
 CPUFreq, disabled all deinterlacers, nothing did help.

 If I can help with something (logs, samples, configuration settings) let
 me know.
