But can you add a channel with out doing a scan, the 722 you can rescan and keep the channels from last scan or just put in a single one with no scan. All this is needed if you have a rotor and change directions for other stations.
One good reason is for OTA tuners for local stations, I record programs from subchannels that dish does not carry. From what I understand the Hopper is not as good as the 622 or 722 when it can not add OTA channels
I have a UN55 JU 6500 it was a replacement for my Samsung 8500 plasma and have a dish 612 and 722. You can get 4K with the JU5500 from Netflix and Youtube . If I could I would go back to my 50in plasma see how this 4K works out,
