I am a new pro-hd user. When I am watching on a remote laptop the host television changes channel to the remote selection. Can the host television be tuned to a different channel than the remote and if so how?
Depends on your TV source. If the TV and the Slingbox are using the same TV source (cable, satellitte?) then inevitably changing one will change the other, laws of physics
Think of the Slingbox as a TV that just happens to to send it's output down the Internet instead of to a screen. So you need the same equipment (extra cable box?) you would need if you wanted to add another TV to your system.
