Ok, I got my 222 to work on tv1 with the uhf remote they supplied for tv2. It was very easy just setting the switch under the blue tab. I am able to use my uhf 4.0 remote that came with my 322 for tv2, but not tv1. It seems only the 6.3 uhf and higher remotes work on tv1. They are both uhf pro, I don't get it? On the system info screen it says uhf pro tv1 and tv2 with different addresses. On my 322 I can use the same remote (4.0) with both tuners. Any ideas?
