Ok, I finally got the inputs on the TV to behave properly and they switch quite effectively between 3 devices, however now I have a weird problem that has me stumped. If I do an activity like "listen to radio" or "listen to CD" that has absolutely nothing to do with the TV, somehow the input selection gets out of lockstep with the remote. Very strange as the TV retains the last input it had when it is powered off, as it is when these activities are run. Thanks for the help.
