I have two HR 21 HD receivers both have the same problems with autotune feature. If you auto tune a future tv show then turn off your box it and wait till show comes on it will just black screen, you have to type a channel number to get it working again to see a picture. Also if you leave the box on it will auto tune that channel with no problem? Does any one have this same problem? I did not have the same problem with the SD receivers.
