I have a shiny new phenom ii x4, and I'm still having the same problem I had with my old 5200+, which is that 1080p mkvs can't be transcoded fast enough. the buffer is always empty. I thought maybe it was the cpu, but since it's still happening, I'm at a loss. I tried several different options with the old processor, but this machine shouldn't be having any trouble. right? I'm on a wired network, though i don't think that has anything to do with it.
