Check out Broadcast Machine, a tool that allows relatively easy video content publishing. This is php based. RSS + .torrents = the tivo-ization of your computer. Whether it's this app or another, this stuff is basically ready for primetime now for technically proficient folk. You'll spend more time figuring out how to get the appropriate video and audio codecs going than you would getting your pseudo tivo working.

Note: this is a publishing tool. It will help you to get your content out to the world.
