Hi!
Searched the forum for an answer and did find this:
"There are two distinct Mode settings you can change: one for the Info Bar (this controls the channels it will flip through when you use the Channel Up/Down buttons) and one for the Guide (this controls which channels are made visible in the various Guide screens.) Both Mode settings can be changed independently of each other.
To change the Mode for the Info Bar, press the right arrow button while watching live TV. The Mode menu will appear. Once you've selected a mode, using the Channel Up/Down buttons will only flip to channels that fit the Mode you selected. You can disable the Mode for the Info Bar by pressing C (hence the "Press C to disable Modes") message."
When I press the arrow up button I do not get a mode menu. I do get yet another iteration of the channel guide showing on the right side of the screen. There are options for that, but nothing that suggests to limit channels to subscribed channels only.
I did manage to get the settings right for the guide (when pressing the Guide button), so that is all set, but that did not have any impact on the Channel + / - buttons.
Any advice for this?
