hey man, I currently have both of them for a few more months. I just got DTV HD and love it. HD is great, I know that discovery HD is a channel that you can get. Right now they are running a special where you can get FREE HD Package for 3 months, FREE ENCORE/HBO for 3 months. Along with all your other stuff. Music channels are a lot better on Dish Network just because they have Sirius radio. Also, if you are into sports, and especially NFL. You will want DTV and Sunday Ticket. Anything else, just ask
