Odd. I'd expect very little load on the second core. What is  
mythfrontend using under "top" and what processes are second and third  
in CPU use.

I was hoping for a bit under 87% load as well, more 70-75% given the  
speed bump over a 3600 X2.

I'm not having that issue. I set a series of programs to record last  
night on the test rig. Three off a single DVB-T tuner and three off a  
single DVB-S tuner. Recorded all six programs simultaneously so the  
backend is fairly robust. The frontend crashes I'm getting are usually  
during live tv.

Might be borderline. Can you post the CPU identifier or confirm if it  
is a 65W part.

Also how much Ram have you got in the box.
