I have some older series 3 HD TiVos that have standard remotes with the 1-2 switch to allow one TiVO peanut remote to control two TiVOs. These older series 3s are all in basement rooms and lightly used on a daily basis. I now also have a 4-tuner premeire in our main bedroom, but am using an older Series 3 (OLED) glo remote with it. All works good. I was thinking of moving one of the older series 3 TiVos from the basement and stack it on top of the bedroom's 4-tuner Premiere, but then wanted to somehow use only one remote for both. Is this possible with the Series 3 GLO remote or does the remote HAVE to have that 1-2 switch in order to be able to do this?
