How can you get the flv of a MySpace video given its ID?

For example, sites such as keepvid.com generate video download URLs for MySpace.

I know how to accomplish the above for YouTube (there’s an swf “t” argument in the video’s page, and the download link is merely http://www.youtube.com/get_video?video_id=<id>&t=<t>, where <id> is the id of the video and <t> is the “t” argument – just use php’s file_get_contents on the youtube video page and preg_match/regular expression), but for MySpace videos, I’m baffled.

Anyone have any idea?

Thanks for the help!
