I tried searching for this, but came up empty. We haven't been able to use second sat tuner for the last couple of days. When we record a show the receiver forces us to watch that show or an OTA, but not a second sat show. If we try to go away from the show that's recording the "do you want to cancel recording" comes up. Are we doing something wrong? This seemed to work ok just a couple of weeks ago. We have only had the 722 for a month and I had already recorded 2 sat and 1 OTA at the same time with no problems, but now it won't. Any suggestions?
