This link gives info on what is needed to view HDTV in regards to video 
card and cpu, along with other info.

If you search around on that wiki you will find info about cards to use 
to capture tv.

I am using a pcHDTV HD-5500 
http://www.mythtv.org/wiki/index.php/PcHDTV_HD-5500
I am pretty happy with that, and it is working well with my myth tv box.

But I now need to build a box (and get a hd tv) so I can view the shows 
on something other than my computer!

I also talked about MythTV last year at a Penguins Unbound Meeting, here 
are the notes.

Good Luck.
