Point to Youtube & Google video files in RSS feed

Miro (formerly Democracy Player) is able to download youtube & google videos that are embedded in feeds. I was thinking that this would be a good feature for the video module as currently youtube & google videos have broken media enclosures that link to non-existant links.

I was going to test some code out and see if it is possible to modify the creation of the media enclosure if the type is a youtube or google video and instead link to the video on the youtube or google site the way they are referrenced by the feeds created by youtube or google and then put them in the feed so that Miro can download youtube & google videos in the video feed.
