quick question on the 622. I know that tv2 uses the uhf remote so it can be used in another room. can the main tv1 remote be used in a uhf mode? I have a home projector screen that drops down out of the ceiling and it covers the IR eye's so only uhf will work when I'm using it. would I have to buy another uhf remote or can it do that out of the box (2 uhf remotes). thanks! installer coming this week.
