The cpu usage on the mac-mini is ranging around 35-50% on each core
during playback of 720p recording so I think it's got enough power.
The big issue with the mac-mini is the i915 graphics, but I've never
really had a problem, until the a/v sync issues popped up on the one
channel. I'm going to try and get the display frame rate figured out.
On a sidebnote I recently picked up a pair broadcom cyrstal hd cards
for an appletv and for the mini just for the hell of it, though they
won't be much use for mythtv for a while from the sounds of it.
I appreciate your help, I'll keep after the ghosting for a bit.
