Better Golf Videos - USB TV Tuner For My Laptop

I record alot of golf footage for this blog as well as video for my other blogs and it's come the point where it's been getting harder to record video because of the different applications I use and the restraints on them. Along with the inability of my current video card to record video straight from my t.v. Well I've been doing some research into USB Tv tuners and this might be the way to go most seem ok but with research I'm trying to find the best one for my current uses. Will keep you posted.
