When I was doing CPU decoding of HD-PVR recordings, whether or not the
CPU could keep up seemed to be dependent on the particular content more than
anything else. Things like fast pans seemed to really be a problem. At the
same bitrate, some shows would be fine while others would stutter.
Although I never tried to tweak my bitrate on the high def stuff.
