I have read about this problem. Apperently some AMD processors throttle the bus speed along with the CPU clock. They say to play with it to find a value that works well for you.

It does handle the mpeg2 stream in soft mode better then the gpu, but it runs the cores at 80-90%+ so not much head room left.
Hmm. I wonder if the issue is the 8400 doesn't have enough horse power to both decode the HD MPEG stream and down convert it to SD. Have you tried it on a 1080p display to see if you get the same problems?

One question, you say in your previous post that you are using 1/2 spatial de-interlacing. Why bother de-interlacing at all if you are down converting to SD (which is interlaced)?
