Mine has been working fine (Cablevision/TivoHD), but theres still the problem with it only being able to tune two channels at once. This isn't a problem with the tivo, But I was considering the 3 tuner moxi and a moxi mate for my mother until I read that it would be stuck on 2 tuner if you plug in a Cisco tuning adapter. Apparently the moto tuning adapters don't have this stupid limitation.
