The situation is as such: Current setup includes 3 tivo units, on Rogers cable. 2 units using rogers digital boxes, on unit using regular cable.
If I can get listings for the IPTV lineup, The signal out of the Bell box could go through the tivo unit. This assumes that tivo has the IR codes to control the bell terminals.
I spoke with someone at Tivo about this, and there position was that they did not wish to support IPTV at all, no matter who the provider is.
Our preference for the Tivo boxes is the one thing keeping us from switching to Bell IPTV. Frankly no other pvr is as usable as the tivo, nor has the great user interface.
