Comment 1 for bug 1564189

I too experience this, although I don't believe it is solely related to TWIT Security Now. I sometimes get this issue with Linux Unplugged.
In the past I have closed all the applications and restarted the device, and sometimes ( 50/50 ) it fixes it.

What I also found was that, if you set it playing and then leave it, after a minute of 2 it suddenly starts playing the episode.
