To the best of my knowlege, the THR22 (Tivo Box) is not whole Home capable. Also, it requires a phone line to be connected for TIVO services.
Just a couple things to keep in mind, when thinking about getting one. Oh, and somebody else posted that CSR's and Techs really dont know much about the TIVO's... They're right. Our training was minimal at best.
You are correct, the THR22 is NOT Whole Home capable.
