[mythtv-users] Minimum CPU for separate backend

[Stephen Tait]

>For a pvr-x50, a 233MHz should be completely fine for a backend.

Like everyone says, most backend processes use little or no CPU. Commercial 
detection and transcoding do benefit from fast CPU's, but pretty much any 
processor from the past 6 or 7 years should be able to handle the bulk of 
the backend work.

Different PCI revisions usually have the notches on the the PCI slots in a 
different place so you (usually) can't physically fir the card in. The 
first board I tried my 250 in didn't show it up either; this was due to 
there not being enough free IRQ's to give the 250 one to itself.
