My Wife is hard of hearing and relies on Closed captioning to be able to watch TV. 4 times now since having Dish Network, and I have only had it a week, Closed Captioning has quit working on my 522 and also on my 322. To get it working again I have had to hold the power button in for about ten seconds to reset to receiver. Is this common? If it is Dish Network is just not going to work for us as my wife has to have this and I am not going to go to the trouble of resetting receivers 4 times a week. Any thoughts?
