Did some room & furniture moving, including moving my newer HR23 box upstairs to bedroom where I had the HR20. Still on single cable no new cables, but it was set for two tuners so I had forgot about that and reset system. Then my son reminded me I only have one SAT cable in the bedroom so I did the dish setup and specified One tuner and it rebooted and I got signal strength fine and about half my channels. All channels are listed in the guide, but about have have no programming information in the time slots. I know this is either the time it takes to rebuild the guide or maybe some setting that is blocking half my channels. Should I just wait 24 hours or is there something to try?
