Hello everyone,
Happy to report that I have been able to get the Flipper remote working with my Virgin 360 box. ๐๐
For completeness and to help others I am going to list out all findings:
Set up is a Sony TV and STB a Virgin Media 360 box. The Flipper remote control is V9.6.
I was able to get the Flipper to control the Sony TV very easily by just punching in one of the codes. The Virgin 360 box not so easy.
After trying all sorts of different codes, including those given by Flipper support, nothing was working.
I then did a code search as Flipper and Roger_Gooner above stated and followed the instructions as per the link kindly provided by Roger above.
The second lot of code search codes sent got the 360 box to power off.
Therefore, the 360 box DOES have Infrared capability, which is contrary to what Virgin Media told me.
Also, the Virgin 360 remote still works, so what others are saying about it only being possible to have one remote paired at once to a 360 box is incorrect.
I am very happy, as is the disabled person in the house who is now able to control the TV.
The Flipper remote works very well, the volume buttons increase or decrease the TV volume and the Channel forwards and backwards buttons change the 360 channels forwards and backwards. The power on / off button when pressed powers off both the Sony TV AND the 360 box, which is perfect.
Thanks for all your help and happy new year!
