isPlaying() behaviour across backends

[Frosty-J]

Have I got it right that isPlaying() returns true when paused on desktop, but false on the other backends?

I discovered this when I was testing pause functionality and couldn't get the pause status out of the desktop video player.

Hmm yeah, that shouldn't be. I think the easiest way is to change it to playing && !paused
