OK, sorry I just realized that you are talking about doing HDTV.

In that case, you will likely have to go with the high-end P4. Playing
back HDTV signals takes a lot of processing power. I'd be surprised if
the 2.4 Celeron could handle it. The 1.8 GHz Celeron certainly could
not.

OTOH, if you're not planning to play back HDTV using this box, then
you could easily go for the 1.8 GHz Celeron. And it should be much
quieter than either of the other two options. Recording MPEG streams
from the PVR-500 or the pcHDTV takes minimal processing power. (Just
as a side note, you should be aware, if you aren't already, that the
PVR-500 currently has alpha-quality support in Linux.)

Hope that helps.
