I have a Sony A/V receiver (STR-DG820) that I can't program to my Hopper remote. The code for the Sony was 766 for my old DISH 21.0 Remote and never had a problem from day one controlling my 622. This Hopper/Joey 40.0 seems not to have many codes built in, and it wants a four-digit code. The DISH tech tried for a long time during the installation (he tried look up on-screen and tried to IR pair with the 21.0 to no avail) on my Hopper and Joeys this afternoon, but I told him if he stayed any longer I would have to charge him board and room. I've always had problems with my other Sony receivers and DISH remotes prior to the 21.0. Any help will be greatly appreciated.
