The TiVo Stream lets you stream recorded and live TV from your TiVo DVR to an iPhone, iPad, or iPod Touch via TiVo's iOS app. It can also be used to wirelessly download programs straight to your iOS devices. (An updated Android app to work with the Stream is in the works.)
Once connected to your network, the Stream starts hunting for your TiVo. If all goes well, you'll get a solid white light on back. There are no lights on front to let you know you've got power or you're connected; everything's on back.
