Does anyone know a code that prevents a PVR3 RCU from controlling an HD box through RF2 and prevents it from controlling a pvr3 directly at the STB, but allows it to control the PVR3 through the magic eyes. This code exists, both myself and a colleague in our wisdom thought we were helping by resetting the RCU to default (i and select, 1 select) I have a customer who has both a pvr3 and 4 running throughout the house on RF 68 and 60. Through one magic eye (daisy chained i presume, didn't venture to the amp) My colleague recfitied the unrelated fault on the PVR4, then created another one by defaulting two of the PVR3 RCUs. I defaulted the third trying to fix the fault. I have tried all the i and select codes and the select and coloured buttons codes to no avail. any info or link would be very much welcome and appreciated.
