If you still have the option to return the ATI650 do so. It has hardware issues and software issues. Don't waste your time on that product.
Hauppage 2250 is the best dual tuner HDTV that you can get. Its hardware is very reliable. Its software works well on its own or it works well with Windows Media Center.http://www.newegg.com/Product/Product.aspx?Item=N82E16815116036
