Im using a Tivo Slide Pro with my Roamio and a new Sony receiver. Ive got it paired fine to the Sony but the range is very short and wont work with the cabinet door closed. I asked the installer if he could get the volume working with more range. He said the Roamio does not have an IR out that could be used as a blaster to connect to the Sony receiver. Hes saying he needs to add an IR receiver to the Sony to get this working. Is this correct?
