[mythtv-users] is my processor to blame? (lockups, problems with FF and REW)

Here is the info from my lspci -v Kenneth.

Some notes on my system.

I don't have an onboard anything on this system. I have lan, sblive,
pvr-350, pvr-250, and nexus 2.1 as well as an nvidia geforce 3 500. I
run video out from the 350 into my tv, as well as the audio. I'll be
switching my audio to pump through my sblive card this weekend when I
get some cables.

I can probably disable com1 and com2 to free up IRQ 3 and 4 if that
seems to be the problem.

I don't have a keyboard or mouse plugged in, nor do I have any usb
devices installed. It's just a box by the tv.

thanks.
