Hi, I was just trying to provide a link to the Elgato site which describes the EyeTV Home, and couldn't find it. This little device looks like a normal EyeTV 410, but is actually a media centre that allows you to send programs recorded onto your Mac to TVs in other locations within your house. The reason for including the Aiport express is that if you don't have cabling in the room, you may want to receive the signal wirelessly. cheers, Susan.
