[mythtv-users] Time for new hardware. CPU HIGH loads

I've noticed a high CPU load since my last SVN update as well (158xx).

My X2 4000+ can no longer keep up with HD 1080i cable channels w/ any
deinterlacing, or do Yadif 2x deint on SD content recorded from my
PVR-500...  In both circumstances, load goes beyond 100% (one core fully
loaded) and I notice significant stutter.  Both were fine with well under
one core used a week ago.

I miss my Yadif 2x on SD content!  Made it look so much better on my HDTV.

WAF is falling :)
