My setup:
I have my pc in the basement, where the Time Warner cable tv cable comes into the house, and take one of the cables off of the splitter and hook a cable directly into my ATI card, and cap directly into the pc. I need to clean out my hd, only have about a gig free at the moment.
I'm using a 1ghz Athlon, 320 megs o' ram, with an ATI All-In-Wonder Radeon card. I believe the video card is capable of up to 500 lines of resolution, don't remember for sure. If I had an empty 30+ gig drive, I could record whole movies to the hd, the ATI card comes with its own version of programmable tv software.
I lost a bunch of A&E's Cleavage screen caps last night because the damn pc froze up on me, happens occasionally. I defragged my hd two months ago, and now I'm dropping frames sometimes on vidcaps, go figure. I also get better reception on some channels than others, been considering going to a dish setup, most people I know that have them like 'em.
I'm also lusting after the new ATI 9700 All-In-Wonder card, would buy one if I could round up the cash, but any money I have right now is goin' for presents to others.
