Sounds cool mate. Well, the quality isn't that great, i hope you don't mind me saying that :<
But if you do buy a HD PVR go after a HAUPPAUGE HD PVR. It's pretty good. It can capture in 1080p. I'm thinking of buying one myself so i can upload some of my good runs in Ninja gaiden and share it with my friends on youtube

And it's cheap too! You can get it for about 100 bucks on Ebay. (if you are lucky) a new one costs about 200 bucks or a little more.
Btw, i subscribed you ^^ 1 more is always something :p
