I just got AT&T Uverse with a Cisco IPN430MC Reciever. I can't seem to get my Channel Vision IR-5000 IR repeater to work with the new box. I've read that the receivers IR sensor is really sensitive and/or has a special frequency. I've tried putting scotch tape over it, moving the transmitter around, black tape with a hole over the sensor, etc, and nothing seems to work. I know that the IR-5000 is getting the remote signal and the system works fine with my LG Blueray player. Any other suggestions would be helpful as I would rather not have to buy a new repeater!
