A lot of movies end up encoded in mpeg2, rather than the high 
compression H.264 or VC-1.  With your 8500 (and a commercial decoder), 
you get quite a bit of offload to your GPU.  If I had to guess, I would 
say you're using PowerDVD for BR playback, and just a free CPU based 
decoder for file playback.

Just as a point of reference, my 2.2GHz C2D under Windows with ffdshow 
(variant of ffmpeg) is good for ~10Mbps per core.
