I have watched quite a few episodes via my Tivo. While it can currently pull them from YouTube, the changes to the names of the YouTube episodes that have occurred over the run make it is quite difficult to find each and every episode of KPCS. Doable, but difficult.
Ideally you could set up an RSS feed to download the episodes directly to the Tivo and bypass iTunes. Once this is done, the episodes are downloaded over the Internet as they come available and they appear in the "Now Playing" list like any other TV show. If you post instructions for the user, it is very simple to set up. The only catch is that the publisher (in this case the KPCS crew) needs to publish an RSS feed (insanely easy) and encode the episodes a certain way (difficulty depends on your production setup).

Love the show, keep it up!
