iOnTV requires Mac OS X 10.5 (Leopard), and is available for download here.

A smart recording feature will also let you record all programs that include a particular performer, or all programs for your favorite sports team.

Recorded programs can be converted and inserted into iTunes so that they’ll automatically be available on your AppleTV or will be synced to your iPod or iPhone the next time it is connected.

Best of all iOnTV is free and OpenSource, you can download the latest binary package from here, or get the sources from here.
