Can anyone answer my question about how to access video options during playback and why the aspect ratio key toggles sleep mode instead of the aspect ratio? I'm sorry if this is explained somewhere obvious but I have searched and can't seem to find this information.

Can't answer the sleep mode thing (I assume button remaping) but for the way to get options you should hit the information button (i) and when the usual stuff about the episode/show comes up, use the directional buttons (up, down, right left) to move to the left. This should display a side bar on the vertical left side of your screen. There should be a button for player controls, which should bring up the standard playback control for your Kodi system theme and you can make your way to the settings you need.
