I'm confused by the Blue-ray FullHD Video Playback CPU Peak processor load figures. I have seen figures as low as 1-2% CPU usage on a 780G system with a much less powerful processor (Althon 4850). My guess would be that the test's H.264 decodeing was being done on the Phenom, not using Avivo HD or Purevideo HD. If so this is a very misleading test.
About that other post. H.264 is entirely decoded by the GPU, while Blue-ray has to be first decrypted by the CPU
The test showed a 4 core processor using 33% of CPU, I would not expect decryption to be anywhere near this expensive. On the other hand 33% CPU sounds like a plausible figure for software decoding of H.264 (or maybe VC-1).
I'm not claiming to be an expert but my personal experience is that hardware decoding took some effort to get working, thus given the figures I am suspicious of this test.
