Thanks Mike for the explanation, I appreciate it lot.

I have a Atom CPU, so "Slim" don't work well (lots of playback stops),
I am trying "VDPAU Slim" and is working great (30 min). I have this

Decoder: NVidia VDPAU acceleration
Max CPUs: 1
Deblocking filer: enabled
Video render: vdpau
OSD render: vdpau
OSD fade: enabled
Primary deinterlacer: Ninguno (none)
Fallback deinterlacer: Ninguno (none)
Custom filters: vdpauskipchroma,vdpaucolospace=auto

Is this correct? Need I an extra driver/xorg configuration?

I appreciate lots your help, I am getting this problem for a while.
With the last nvidia drivers I have less playback stops, is a random
problem. I can not reproduce, just fails sometimes.

Best regards.
