Maybe you can! You can also use the Hauppauge DVR with your DirecTV HD receiver if you don't want to pay the DVR fee plus $199 up front. As I read their literature, the Hauppauge DVR will even change the channels of your receiver for you. The question is do you want to go through the rigmarole to make it work? If you are hot rodder and want to put Chevy small block engine into your '32 Ford Deuce coupe, you certainly can. It's been done hundreds of times, just like I'm sure there are many folks on this board who use the Hauppauge DVR with their DirecTV HD receiver.
