I'm looking for an easy way to manage my playlists which include videos from Youtube, Blip, Vimeo, and other sources.
Tools like Embedr, Yubby, iDestop.tv, etc, can create playlists from multiple sources. But, as far as I can tell, you're locked into using their player.
Feedbeat.com is the only tool I've found that lets you build a playlist from multiple sources AND generates an XML feed compatible with JW Player. But the interface is a bit clunky and it doesn't seem to be widely used.
Are there other tools that can do this?

Bumping because I can't believe there's nothing out there. Or does everyone edit their XML playlists manually?
