I had an additional receiver (old model 2000) installed in another room. Previously I just had one receiver, a 721. When the 2000 was authorized it now provides me with all of the Superstations which I do not subscribe to.....just America's Everything, my locals, and two groups of distant networks. Anyone know how I can get these channels to come up on my 721 guide? I don't want to discuss this with a CSR since they might remove them entirely.
