Hi TiVo Folks, Sharing this in the hope it may help someone else. I received a new Roamio Pro this week and had all kinds of trouble pairing the remote(s) in RF mode. I had the remote that came with the unit and had purchased a slide pro to get the keyboard. After spending a bunch of time trying to get them to pair, reading these forums etc... I finally broke down and contacted TiVo support. After >1 hour on-line trying all kinds of things we started turning off other items that could be interfering with the RF signals... eventually a Comcast DVR box sat on top of the TiVo Roamio was turned off and the pairing worked just fine... and since then all devices powered back on and both RF remotes are working just fine. So the moral of this story is the Roamio Pro appears to be susceptible to RF interference (specifically during the pairing mode). Regards, Jeff.
