Many people have talked about how if one tuner is recording a HD satellite program that you can't change to an OTA digital channel without first stopping the recording of the HD satellite program. You can, but you need to do one more step to make it work. If you are watching the HD satellite channel being recorded, to change to an OTA digital channel, you must first switch to the OTHER satellite tuner before you can change to the OTA 8VSB tuner. To do this, press CHANNEL UP or CHANNEL DOWN. Not only will this change the channel being displayed on your television, it will switch satellite tuners, so the original tuner is still recording the previous HD channel, but you are now watching the other satellite tuner. Now you can punch in the OTA digital channel you want to tune to, or scroll to it. Note - this method does NOT work if you are recording 2 HD satellite programs. If that's the case, you cannot change to the OTA tuner unless you stop the recording one of the satellite tuners.
