I also prefer to stop the video when pressing back so I added this my keymap -

xml:
<?xml version="1.0" encoding="UTF-8"?>

<keymap>

    <FullscreenVideo>

        <keyboard>

            <backspace>Stop</backspace>

        </keyboard>

    </FullscreenVideo>

</keymap>

If you don't want to mess around editing keymaps you can also use the Keymap Editor addon - just edit the 'fullscreen video' back function to stop.

 

I use a keyboard for my remote control on Windows 10

I added the following to my keyboard.xml within the <global> <keyboard> section

xml:
<a mod="alt">xbmc.playercontrol(frameadvance(1))</a>

This is frame advance. When you pause, press ctrl-a the osd will disappear, and the movie will advance one frame. In most cases the frame advance won't be a problem unless you happened to pause on the last frame before the subtitles disappear.
