Hey, I'm using your great new control which does just about everything I want it to. I am having a couple of problems however. It is probably my lack of knowledge. Be that as it may, Here goes...
I'm using the play as a control in another SL4 app.
If I add a playlistitem to the playlist, and it has the mediasource defined for progressivedownload, sometimes it doesn't start downloading immediately. In fact, sometimes it doesn't even make the request to the media source (I've seen this in fiddler).
Along these lines, I would also like to be able to set the mediasource for an existing playlistitem in the playlist and have that start the download. This works sometimes, and not other times.
I would also like to be able to handle the play button click event so that I can set the mediasource if there isn't one already.
