It's come to my attention that Google is having some trouble playing video that has been uploaded (not embedded). I'll try to get this taken care of. It seems that Firefox plays them fine though, at least mine does.

This was the problem I alluded to in a Facebook message. I use Google Chrome as my main browser now because it moves faster, but none of my uploads play. I thought it was only me, but I can see others are having a problem, too. I'm not alone.

I'm thinking it has more to do with the Flash-based codecs of the videos that jwplayer are playing. As of Chrome 53 it blocks Flash due to how insecure it is.
