You can set subtitle settings in the main Kodi settings. Or you can click the select button while watching a video and choose to disable subtitles each time.

I can't seem to find the select feature here. Outside of PSTV I can hit "m" and get the menu to change audio tracks and subtitle option but nothing happens when I hit "m" but a flash when in PSTV and a lot of my videos are playing commentary tracks instead of the regular track and I have not figured out how to switch it because shortcuts I have created for outside PSTV don't work in PSTV. Is there a list of shortcuts that work in PSTV...so far I know Play and Pause seem to work the same and "x" stops/exits for me. "s" brings up the shutdown dialog and "i" brings up info and enter takes you to he EPG. That's all I know.

You will need to use the keymap editor addon. You have to set the key as a global key in keymap editor to get it to work in PTVL. I have set the T key for subtitles and an unused key for audio. So although the T key will already enable subtitles while watching a video in Kodi normally, you will have to set it as a global key for it to work in PTVL. Same goes for audio.

6 months on, is there an elderly-compatible solution to this? A way to make the UI look exactly the same as the stock TV UI? Remapping keys and expecting my stubborn, lazy 65 year old father to understand how it works isn't going to fly I'm afraid. They need to see stuff on-screen.
