I don't know if this is relevent, but I am using a 6200 GPU with the
9631 drivers and am getting all sorts of prebuffering pauses (one every,
say, 30-60 seconds) that I never used to get with my 5700 GPU and the
earlier drivers.  Yes, I realize there are many variables here, but the
newer card/drivers performs worse than the older card/older drivers.

I have absolutely no special settings in my "Device" section in

I am not doing any HD, just playing back recordings from my PVR-250.

Any insight would be greatly appreciated.
