I have tried to watch 3 different shows today off the dish on demand (I have a 722K). Each time everything appears like it's downloading but when I try to watch the show all I get is a black screen. I tried to watch while it was downloading, and also waiting for it to finish. I show having a rental but when I try to watch it is 30-45 minutes of a black screen. I tried a hard reset on the unit but that didn't seem to do any good. I tried from 3 different networks and it was the same each time. Anyone else having issues?
