our dish network duel tuner suddenly won't let us watch different channels on

[SteveandKarenCovington]

two tvs.. help? We have had this issue a few times before. There is one 2 way tuner for our dish network that is shared between two bedrooms (there is a another main unit in the family room), this tuner is supposed to allow you to watch different channels on the different tvs. Well today, went upstairs to watch TV and I ended up changing what our roommate was watching in her bedroom. Can't get it fixed. Changed all the modes around and around. Nothing. Help?
