I just installed FIOS. I have a Series 2 as well as a Humax Tivo Box. On one TV, I have the series 2 hooked up, but not through the FIOS TV box. The Tivo works fine (although just getting limited basic channels). It is recognized on my home network (i.e. viewable in Tivo Desktop) without issue. The Humax Tivo is connected through the Motorola FIOS TV box. This Tivo will connect to the internet properly to update, although I can not seem to get it to be recognized on the home network (as such, nor in Tivo Desktop for that matter or viewable on the other Tivo box). Is there something funky with FIOS that if you connect through the box, networking options become disabled? Thanks.
