Please clarify what you mean by "on a regular basis"
Does it work sometime
did it work at any time in the past; once????

I have another problem. Initially, my harmony worked with the dish receiver. Over the course of time, the dish remote started to malfunction (couple of keys died) and I got a new dish remote. The new remote had to be 'set up' to work with the dish receiver. The harmony stopped controlling the dish receiver after that. Digging around the various forums and blogs, my understanding is that the remote and receiver must have the same 'identifier' in the IR signal. If they are out of sync, the receiver will not respond to the remote. I suspect this is why my old dish remote will no longer control the receiver. You may have the same problem.


Your quote from another post
When I use the original Dish IR remote I need to be very close for it to work.
Do you have new batteries in the dish ir remote? The dish remote is quite powerful and should easily work at about 20'.
If you have to go down to 5' for the dish remote to work, I agree, you may have a bad ir receiver in your 722.
