I have been working on syndication stuff for last some months. I learnt about different standards (feed formats, microformats etc). One of those is Yahoo! Media RSS, which is module (or extension) of RSS 2.0.
Definition (from MRSS FAQ):-
"Media RSS" is a new RSS module that supplements the enclosure capabilities of RSS 2.0 (FAQ).Enclosures in RSS are already being used to syndicate audio files (Podcasting) and images. Media RSS extends enclosures to handle other media types, such as short films or TV, in addition to providing additional metadata with the media. Media RSS enables content publishers and bloggers to broadly distribute descriptions of and links to multimedia content.

YouTube!, Flickr, Google Video, Yahoo! Video, Grouper etc are exposing their content as Media RSS feeds.

I have also extended (locally) Adobe AS3 Syndication lib to support Media RSS module for one of my projects. I need to submit the code after testing. I hope, I get sometime to do that.
