What brand of TV? Flat screen? Does the TV have a feature known as "backlighting"? Experience has shown that large flat screen TVs with backlighting can cause some pretty severe IR interference with the #1 IR remote. As others have said, if you have a remote that is IR/UHF, you can change the switch back where the batteries are to UHF, press "System Info" on the receiver, then press SAT then RECORD, and it will re-address remote #1, and will make it UHF. That will often cure issues with remote #1 and IR interference.
