I'm happy with my Hauppauge 2250; it is easy to install and use, is Windows media center compatible, and gives good reception on all the analog, HD, and unscrambled QAM channels. I only have cable - no set-top box and no antenna. You have to buy WinTV7 from Hauppauge for $10 if you don't have a version of media center, or another TV program, e.g., BeyondTV. I bought it to see if it was any better than Media Center; it wasn't. Used the card on both Win7x64 and XPsp3Media Centerx86 systems. I had a PVR-500 on the XPsp3Media Centerx86; it's not HD and gave lousy reception on channels 2-8.
