Wiliam, I noticed the TED talks problem persists in FW 1.46, much to my regrett.... I am sure it worked fine a couple of month ago.
Any video selects and loads, but never starts playing back.Attached the console log that leads to it:

Hope you can find time to dig into it....

It for sure has been working but I have the same issue at the moment.

It is possible that they changed something on the stream and we are not picking that up correctly.
Will check it.

It's a great and wonderful thing that there's a TED Talk player in the ListenLive application set.  Thank you!
