Looks like myspace videos have stopped working again, even on their own site. I contacted their support and reported the problem. I'll wait until I hear back from them. I'd hate to delete all those good videos so I'd rather wait a while longer. Thanks for your patience and understanding.
The reply from myspace is in Unfortunately, our tech team is only focusing on songs/videos uploaded within the last 3 years. There is no time frame of when media uploaded over 3 years ago will be fixed. I am sorry for any inconvenience this may cause.
