	I had a very similar problem just last night. One HD channel would not work, generating
tons of NVP prebuffering errors and then freezing. But only one channel - every other channel worked
fine. I changed my playback profile to CPU++ (effectively disabling XvMC) and the problem went away.
So for me at least, there is something wrong with XvMC but only for one channel. I haven't looked at
it any deeper than that since my frontend has CPU to spare.
