I installed Tivo’s Desktop software on my iMac a few nights ago. It lets you stream music from iTunes to the Tivo, but the interface lacks polish and features.
Tonight I ran across Audiofaucet, a third party program to stream/control music from iTunes or a folder from both Windows and OS X machines. The program has gotten a lot of recognition from the Tivo programming community, and is currently in public beta. I downloading the app and had it running on my Powerbook and iMac in seconds. The interface on the Tivo side of things is very slick, with the polished look of a modern application. Audiofaucet also lets you play audio from your Tivo, or play audio from the source computer. If you have your computer setup to a massive system already, the Tivo can serve as a controller for the computer… pretty slick.
If you’ve got a Series 2 Tivo setup on your network, I highly recommend you check out Audiofaucet at digitaldroplet.net. I’m looking forward to progress from this app, and will gladly pay for it when it gets out of beta.
