I'm not sure that the indep claim covers the way podcasts are delivered nowadays. Claim 1 seems to require a single channel which both provides notification of new content and from which new content is downloaded. But, an RSS feed for a podcast just provides a URL pointing to the content. No one really downloads anything from an RSS feed.
My guess is that if this patent reads on any technology in use now, it's probably something more like dvrs or on demand TV.
Caveat: I haven't read the specification, so it's possible that there's a special definition that I'm missing.
