Then don't, start a new one. ;-)

If you're using the 350 for output, you don't need more than a 400MHz box to 
watch live TV. It does all the decoding work for you, so yes, a 2400 is 
enough. And if you aren't using the 350 for output, I've got an Athlon 800 
that plays back PVR-x50 recordings just fine.

Someone really ought to write a really-detailed low-down on Myth hardware 
requirements for as many scenarios as we can come up with that we can point 
people to, since this is a very FAQ. Did I just volunteer myself? Maybe...

Yes, the encode and decode functions are independent of one another, so you 
can capture a stream and play back a stream at the same time. You can NOT 
record a show and watch live TV at the same time with only a PVR-350 (that 
would be two simultaneous captures and one playback).
