I had #2 with UK SD, post 0.24 and pre BBC One HD, removing vdpauhqscaling seems to have removed #2 for me based on a couple of hours of BBC3 sample, it comes back when hqscaling is back on so I'm pretty confident the sample is enough.

Another possible odd clue is that I used to see a great deal of stutter at the end of each show, specifically at the fade to black and credits, this would go totally nuts for the first 20 sec. This seems better with the local disk build than the nfs boot, just two or three stutters now. This is on all h264 HD channels not just BBC HD so not specific to the BBC's bleeding edge encoders.

Although I'm in the UK, I work with various foreign broadcasters too so I have off air examples of many of their HD transmissions to test with. I'll run through my test library and see if there is any obvious pattern related to rates or encoder manufacturer.

I'm assuming that mythvideo & myth recordings playback are now the same player code with the same setup?
