Don't know about Tivo, but it works fine on a DirecTV DVR.
Make sure that the Ethernet connection on the AirPort Express is working correctly first by temporarily connecting a laptop to the Express Ethernet port. Turn off the wireless on the laptop and see if you can connect to the Internet. If you can, then the connection to the Tivo should work as well.
