I have a ReplayTV connected to the A/V inputs and an SA8300HD connected to the RF input. I had to use the SA8000 STB profile (as the SA8300 remote control is woefully inadequate) for the 8300.

I set the ReplayTV up first. All features are operable through the remote control. I then setup the SA8300 (using the SA8000 profile). Again all features of the remote control work perfectly.

I then went back to the ReplayTV (A/V input) and the "Channel Guide" button on the Replay remote is greyed out. I re-select the ReplayTV configuration and the remote becomes fully functionality again.

I then went back to the SA8300 (RF port) and the "List" button no longer works. I re-select the SA8300 (using the SA8000 profile) and the "List" button starts to work again.

But then the "Channel Guide" button on the ReplayTV remote is greyed out again: and so on, and so on...!

Any ideas why the RF port selection affects the A/V input remote and vis-a-versa?
