Episode 950 (51:08)

Greg from Pasadena, CA
Sony Series II Tivo

Leo says that the System II TIVO does need to phone home every once in awhile to validate an active subscription. According to the chatroom, the Sony Tivo Series II was pretty hackable, while the others weren't. Leo advises visiting and the AVS Forum which can help. It's not really that expensive to just subscribe, though.
