I have a question, I've done some searching around but I think I need some help.

I want to capture footage from regular TV so that I can import it into Final Cut Pro or Adobe After Effects and just play around with it. I'm trying to practice editing and I want to work with some good footage, like CNN news footage for example.

So I assume I just need a TV card. I have a Mac. Does anyone know what is good, and if you are able to download stuff from the TV, would it be easy to convert to a quicktime file for easy editing in FCP?
