When viewing the On Now section, pressing Select or OK on the remote will immediately change to that channel. However, if one wants to see the details about the program in the On Now section, this doesn't appear to be possible.
If you press Menu, Info, or long-press Select/OK, you are presented with a menu:
- Move (if on the Favorites tab)
None of those options seem to offer the user the ability to view a description of the program, to view its start/end time, or to see which tags (New, HD, etc.) apply to the program.
While trying to quickly set something to record yesterday, I selected Record from this menu for the first time, expecting the DVR to immediately start recording, while leaving the UI on the On Now screen. Imagine my surprise when the Details dialog appeared, duplicating the same functionality I would normally have to navigate to the Guide to see (after pressing the Menu of Info key on my remote).
This request is to rename the Record entry in this menu to Details (or similar—nomenclature isn't terribly important), as it is misleading and inhibits discoverability. In fact, yesterday was the first time in nearly 2 years of using Channels that I discovered that this option would display the Details dialog instead of instantly starting a recording in the background!
(Also, I don't know if this applies to the tvOS client, as I do not own an AppleTV. However, on iOS/iPadOS this is moot since selecting an item from On Now on those devices always displays the Details dialog.)
