I can confirm this bug by simply creating a playlist of YouTube videos and optionally save it to disk. even if you just leave the list playing without actually saving it and reopening it later, after some time you will not be able to play any of the links. I think it might have something to do with YouTube sessions timing out. because you search for the same video and add it to the play list, you get a different url.
Maybe a developer or maintainer of the plugin can shed some light on what might be the reason, but I think youtube links are bound to session which expire after some time, never to be used again.
