I just bought an EyeTV package with an HDHomerun HDTV tuner. I have my MacBook on wireless from my airport extreme base station which is connected to my cable modem. The cable modem has one output The HDTV tuner has one output The Airport Extreme has one input and one output Somewhere along the way here I am missing how to connect the HDHomerun to everything. IF I disconnect my cable modem and plug in the HDTV tuner to the router now I have no cable modem. How am I supposed to do this with only one input on the router?
