I have had my 722 for 3 months and have not had problems until 3 nights ago, when TV2 stopped working. I have not changed any settings. Up until 3 nights ago I was able to watch one program on TV1 while recording on TV2 (or vice versa) or record 2 programs simultaneously without difficulty. Now, if I am recording on TV1 and try to change channels, I get a warning that if I do so the recording will stop. I have spoken to tech support 4 times since then and not one has been able to solve the problem. The last one was some out-sourced dweeb from the Philippines who could barely speak English and who was of absolutely no help. In fact, I knew more than he did. During the 4 phone calls, we tried every setting and checked the feeds and signals and also did a reset, but nothing has worked. I feel that I need a new receiver. If I can't get any help, looks like I will be telling DISH goodbye after 9 years and telling hello to DirectTV. If anyone can make a suggestion as to the problem please do. I am tired of dealing with DISH tech support.
