>> [stuff about play next]
> Can you please explain more ?

The code is very short: no key association, you let the next video start
playing and exit within the first 10 seconds breaking the "play next
associated video" loop.

It isn't great but any player could be launched. MythVideo can't know why
[random player] exited, nor will it see key presses while that application
is running.

Play next is how we do multipart grouping.
