        Hmmm, I don't think it's that impressive considering it's
maxed out and people have been able to do HD with lesser CPUs.  Maybe
you misread my "idle" time as busy CPU time?

        I compile my own and periodically update to SVN head  I'm
currently a couple of weeks behind (r12223) but performance has been
pretty consistent for a long time now.

h> Did you compile your own kernel(s)?

        No, regular FC5 kernel.  I think I'm currently one version
behind the latest update.

h> Did make any special tweaks to the settings?

        Nothing special -- OpenGL sync and realtime priority.

h> How did you employ the kerneleint?

        It's in the first page of the TV Playback settings
(deinterlace algorithm).  bobdeint looks better but is too much for
these systems.  I have another system with an x2 4200+ where bobdeint
works fine.
