I can confirm you need to purchase the locals in your package to get the listings in the EPG, otherwise the added antenna ota channels just say 'Digital service'. On my 811, it loaded the listings on most of them. I was told in my 811 days it was something to do with PSIP information transmitted with the channels OTA. But on the 211, it didn't load.
I added my locals to my dish subscription(No charge! I don't know why!), and they immediately were in the 8000's of the rcvr
Funny, it also immediately filled in in the 1-99 range the listings for OTA with the dish listings. I added some the the dish locals in the 1-99 range, 'filling in' the ones I cannot see OTA, by setting a favorite group of a mix of them and OTA, so my guide is now all my OTA, with dish listings, some dish locals I cannot 'see' with my antenna, and the HD channels in the Dish HD Basic pack.
VERY COOL!
