Hi I'm looking to purchase a tv tuner for my computer. I've got Windows Vista Ultimate 64 bit. I only intend to use Windows Media Center. I recieve cable on all my tv's. All I would like to do is be able to watch and record tv on my computer. If possible I would like to be able to watch High defenition on my pc. Should I go with the Avermedia or the Dvico FusionHDTV? Any other brands that you can recommend? Any help is greatly appreciated. Thanks
