I recently had 622 installed, and there was no problem. But the installer did not have a work order to put up an additional dish to get the HD feed on the 129. So I had to setup an appointment, the installer arrived he used a Dish 500 and a DP44 switch with my existing SuperDish. The newly installed 622 picked up all four sats but my existing 811 only picked up the 121 which was on port 1. So the tech decided to try another DP44, no luck. Replaced the barrels, even ran temporary line to the 811, to see if the existing wiring was the problem. Still no luck the 811 only picked up the 121. The 811 when connected to the 622 line it works great. After nearly 3 hours of troubleshooting and two installers later, they gave up and said that they would need to send out a lead tech. Hopefully he can figure out what is going on. Has any ran into this issue, and ideas?
