Pitch and switch, Just pitch and switch....
Call them up and pretend that you want to sign up and get a TiVo, they will point out that the TiVo won't work with the all home system and then they will push there Gennie HR34 on you.
All they do is use the well known brand name of TiVo to draw you in.
When anyone talks about a DVR, they use the TiVo name, "I'm going to TiVo that program" even if the DVR they have isn't a TiVo.
It is just like copers, back in the day anyone talking about copy machines would call then xerox machines, even if they were not xerox machines. Even today, one would say, "I need to make a xerox copy of this", then go to the cannon machine and make the copy!
D* should have to pay a fee to TiVo every time they talk a customer out of ordering a TiVo.
