I was having problems with my 622 rec doing random reboots and losing signals. I called dish last week on Thursday and went through the situation with one of the tech people. I had read some of the older posts in here and I was afraid they would not take care of the problem. To my surprise she said they would ship me out a replacemet reciever. It arrived here on Tuesday but I worked quite late on Tuesday and Wednesday so I didn't even open the box until last night late. I was quite surprised to find they had shipped me a 722 instead of a 622. So this AM I called to see if this was a mistake or not and it turns out, it was. They called it a shipping error and originally wanted me to send it back and they would send me a 622. I was not happy. After a bit of discussion it was decided that I should keep the 722 at no extra charge to me. Thank you dish network!
