Yay for first post!

Alright, I am in need of a capture card/tv tuner that can connect from my TV to my computer and can record video feed to be edited. I plan on using this to watch TV on my computer, and also record stuff (video games, videos, etc). I will get some software, not sure what right now, but first off I just need the right hardware.

I am using Vista Home Premium, and the cheaper the card the better.
