This may help. When I got the Genie three weeks ago I got two of the small receivers that work only off the Genie. I had a problem due to the delay between the Genie tv and the adjacent kitchen tv because there was a couple of second delay at the little, Genie slave, receiver. Normally, this wouldn't bother most people but my wife is constantly back and forth during the day and the same program is usually on both boxes at the same time.
I asked them to give me back a regular receiver that would stay with the Genie, timing wise. They actually gave me an HD DVR in place of the little box. The delay problem was solved.
I'm sure they will replace the small receiver with an old type if you asked. They may even give you an extra HD DVR.
