A quick way would be to put everything in the timeout case of an event structure. When you want the video to play make the timeout = 0. When you want it to be paused set the timeout to -1.
Another quick way would be to link the Play/Pause button to the Increment node you have in there. Put a Case Structure around the Increment. If Play/Pause button is True, increment. If Play/Pause button is False, pass same value through.
I like the case structure around the increment node. Keep it simple. Always a good idea. Just a note to anyone who may find this after: It might be common sense to you but it took me a second to realize this so I'm adding it here... The mechanical action of the pause button must be a switch, not a latch.
