Home BUILT DVR graphics HELP!!!

Ok I am building a DVR out of my pc...How hard can that be?

Currently I have Charter and a MOXI box. It is on its last leg and I do not want the new DVR charter is using (piece of *&^&&*Expletive&&& ).

I have a computer with 2 gig of ram. 4600 Processor. Wireless internet. 1 terabyte HD. Geforce 7800 GT video card with 2 DVI outputs. I Bought a Hauppauge 1600 PCI TV tuner card. Computer is windows XP sp2 (haven’t installed sp3 on it yet).

Ok..Sounds like a good pc? It actually is a nice one. Fast and reliable.

I plugged the DVI port on video card To HDMI port on my Hitachi 57inch projection HDTV. The picture comes in fine. I can see my pc. I loaded the trial of BeyondTV and started watching TV from my pc dvr. It records/pauses and does everything a dvr does.

My problem is that the picture is...ok at best. You can tell there are some lines and major pixilation. It's fine for watching for a few min but I can't imagine watching my shows on that quality. I would rather keep charter dvr.

My question is if MOXi (or any dvr's) can do it why can't I? What video do they use that I need? Surely I can buy something that will work. Do I need a better video card? Do I need a faster video card? What do I need to buy to make the TV look just as good running through my own dvr then the charter dvr?

Also I do not want to listen to regular cable through my digital surround sound (HDMI ...no sound). I want the sound to come through my TV. I really want to use the pc dvr just like a charter dvr. That means I need to go through S-VIDEO and RCA. Will the picture be as good as a regular dvr?

I know someone knows the answer to this. Please help me. My cable bill is 150 bucks a month. With my pc/dvr I can take the bill to 60$.


Thank you
