Not sure if this is the right place for the question or the consumer area. Trying to setup the MRF-260 to allow RF control of my Integra 80.3, Plasma, Sony bluray and Cisco 8642 PVR.

The Cisco PVR and Integra both have IR input connections via 3.5mm cables. But if I plug in a cable from the MRF to the IR ins of those devices, nothing works at all. Ie, pressing buttons on the remote does nothing at all. If I unplugs the 3.5mm cable and point the remote again at the unit everything works fine.

Are there settings in the source devices I need to change as I didn't see any in the Cisco manual or settings ( going through the Integra manual now).

Thx
