We have digital basic via Comcast in Nashville area Current configuration Main tv Coaxial connection giving channels 1-20 Digital box Motorola DCH70 on 1 tv that gives channels 1-70ish, no on demand. Tivo series2 controls this digital box via IR blaster and the normal tivo remote. 2 other tvs Just coaxial connection giving channels 1-20 As of today the coaxial connection no longer gives over the air cables channels. We got for no additional installation/service charge 2 new "digital transport adapters" (DCI105COM1). This adapter has an "IR In" port. My question, can the tivo series2 connect/control two different digital boxs or does one of the two inputs have to be a "it just works" input like a smart card, over the air, or cable over coaxial?
