Ok.. for what you are saying I would recommend
P4 2.4
512meg ram
2 pchdtv or air2pc cards (one for watching one for recording.)
Nvidia Geforce card (Make your own version preference. I'm using an FX
5700LE due to power consumption issues. Geforces are recommended for their
ability to output to hdtv and for onboard encoding to help lower cpu load.
Without a Geforce you will need a more powerfull cpu)
Sound blaster Audigy4 (for 7.1)
I would recommend SATA or SCSI hdd for data rates. It would help with drive
access speeds for watching/recording 2 streams at once. It might not be as
important for OTA as for ASTC over Cable.

If you also want to capture analog I would recommend a PVR-150/250, or 2 if
you ever intend to watch and record analog at the same time. Using a PVR-500
you would only need 1 card as it has 2 decoders and thus can perform as 2
cards. Althou the drivers are still being worked on and many report that
they get no sound on the second decoder. There is a supposed fix for it if
you search the list thou.

For reference, My system
P4 3.2E Prescott(overkill)
512meg ram
1 PVR-350(WASTE as I'm not using the TV Out, should have gone with a 250.
150/500 were not out at the time I built it. Would have done a 500 if they
Geforce FX 5700LE
FIC Condor Case/MoBo using Onboard audio
80Gig and 250Gig Maxtor SATA (80 is about 6g for / with the rest used for
/video and the 250 is all used for /record)

HDTV works great on it but not in Myth at this time. This is not the fault
of Myth but my cable provider. They do not send PSIP data so the auto-scan
detects the streams but can not tune the channels. I am still waiting on the
code to import from the PMT data. Would do it myself if I knew how to code.
