You then get a double playback - and no way to destroy the extra playback without reloading.

So we have to be careful about having good code where this doesn’t happen. I guess this should really be in a bug report.

…

Uncaught TypeError: Cannot read property ‘destroy’ of null h @ wowzaplayer.min.js:32(anonymous function) @ wowzaplayer.js:1(anonymous function) @ wowzaplayer.js:1

custom.js:1820 that was OK
