I going to try something. I had a problem with one of my first receivers it was a JVC digital tape, and it was a real POS! I saw a Charlie Chat where their technical VP Mike Dugan was talking about how great this receiver was. I sent him an email and said "I heard you on Charlie Chat today and you used the Words 'great and JVC' in the same sentence, Surely you JEST! The next day I got a call from him and I told him about all the problems with it, and there were many. He said he would check into it and get back to me. He called back in 3 days and asked me what I wanted. I told him to send me a 5000 receiver (top of the line at that time) and a $350 credit toward programming. He did it! A couple of other time I had problems which he resolved. Now he is CEO of Echostar, but maybe he will be able to help with the sick 722k's. Worth a shot, got nothing to lose.
Michael
Please report back here, if you hear from Mr. Dugan.
