Windows media editions of XP, Vista and 7 should be all you need. If you have 7 ultimate you already have what you need.
Depending on your monitor you picture may be great or it may suck. I dont know.
To use it on a TV, just an HDTV cable from your video card (or an S-video) cord plugged into the back of your TV is all thats required. NETFLIX works the same way also, you can internet stream it the same way. (without a gamer system)
If you do not have these ports (HD or S-Vid) on your video card, get a new one. Most PCI-E cards have them built in. You can also use that HDTV as a monitor if you wish.
ATI has the "All in wonder" video card that works wonders too.
