I have both the Hauppauge HVR-1600 and HVR-2250 in my HTPC. They are both excellent tuner cards. I highly recommend the 2250. I also recommend Windows 7. I was surprised at how well it worked out of the box for a HTPC. I had to do some registry hacks and stuff to get Vista to recognize and properly implement both TV tuners, but Windows 7 worked great without any changes.
