Yeah. And not only that, when in solo mode, the TV2 UHF Pro remote will work fine to change channels on the TV1 output.
Now that worries me, because IIRC both the IR remote and the UHF remote on a 722 by default were set to channel 1. TV1 worked via IR, while TV2 worked via UHF, so the receiver could not get confused about which TV it was controling. This means that you can't even change TV1 into IR/UHF mode without conflicting with the TV2 UHF-only remote. If that collision is now avoided these days, then I'm happy to see it because I had to come here to get out of my predicament when I first got my 722.
