I have the Sony NSZ-GT1 and 2 TivoHD boxes. The Tivos are sitting side by side and I use the 1 2 switch on the peanut remote to switch back and forth between the two units. Only Tivo is connected to the Sony GTV Box. How do I get the Sony remote to control only the Tivo connected to it? Now the Sony remote controls both Tivos at the same time. I have the IR Blaster connected to the Tivo connected to the Sony GTV Box.
