I may well be mistaken but I thought before the 355 update, that I could see all channels that appear on TV1 on TV2 also. I now try to access my OTA channels (which appear on 2-01, 5-01, 7-01, etc on TV1) on TV2 and I only see the Dish Network locals on 2-0, 5-0, 7-0, etc. This is operating the 622 in Dual Mode. Can anyone else confirm my observations? Maybe I need to change something in my set-up menu? Any advice gratefully received.
