When the page with the media first loads it starts auto playing just fine however after trying to "skip" tracks using jwplayer().playlistItem(index); or when the next item in the play list tries to play I get the error,

I have have tried what is on other posts such as making sure the server settings for the MIME type are supported, I have tried running IE in compatibility mode, and i have double checked the javascript. It seems to work fine in firefox, safari and chrome.
