Watching a Rented Movie in "Movies and More" (Dish on Demand)

[MLBurks]

The whole family came over to watch a movie last night. Using my 722k, I went into "Movies and More" (Dish on Demand) to find a movie to rent. We found a movie, rented it, and we all gathered around and started the movie. All of a sudden, the movie stops as it switched to live TV. That was very frustrating. I tried to go back to the movie by hitting the DVR button and selecting "Movies and More". But it wanted to stop recording on one of the tuners. (Sigh) Fine. We went back to the movie. 30 minutes later, it happens again. Apparently while watching a rented movie that is not LIVE off of the sats in "Movies and More", it STILL interferes with both tuners? I can't watch a rented movie that is already stored and record two shows at the same time? Is this normal? When I had DirecTV, I could watch any movie On Demand and that would cause no conflicts with any timers. This just doesn't seem to make much sense to me. Is this normal for Dish on Demand or is something wrong with my system?
