I've used an Athlon 64 X2 3600+ and a Pentium E5200.  Both are dual
core and I don't use irqbalance.

Alan, I think the main problem you and Jeremy are seeing is the hdpvr
can be finicky with some USB chipsets/motherboard implememtations.  I
had some issues which cleared up when I switched my backend from an
ATI 790 based system to an Intel P43 based system.

Of course, I still see periodic hangs and restarts when using the
spdif input.  I researched that yesterday and that's a known problem
even with the Windows drivers.  The cause is probably incorrect audio
encoding upstream or flaky audio output on the STB.  Either way, it
looks like I will have to use the analog audio input if I want
glitch-free video.
