In simple terms, a podcast of any kind (audio or video) is in essence
a media file delivered over http as a downloadable 'enclosure' item
listed within an RSS feed. A podcatcher (such as miro) is given a
bunch of those RSS feeds (which are xml text files also delivered over
http) and scans them for any new enclosures not yet downloaded. The
software then (based on your preferences) will download the enclosures
completely so you can play them 'offline'.
Compare that to youtube which is designed to be streamed. You visit
their site and watch the video in a browser based flash plugin as
opposed to downloading them. That said there are ways and means to
download video from youtube, and indeed miro can do that too.
