Just a bit of an update with the lack of 2 remote pairing. I spoke to someone at VM who has contacts with technical support team the new 360 remote no longer uses IR (infrared) but now uses RF4CE which is a two-way protocol. So basically you won't ever get to use 2 remotes on the 360 Virgin media V6 box unless you use the all in one remotes mentioned previous page.
I suspect its due to the microphone being 2 way, they needed the two way protocol. Sky Q customers face the exact same issue and have had to resort to all in one remotes also.
I bought an One for All URC7145 Evolve 4 remote but the one for all urc7125 should work fine also. Followed the instructions to pair it to my TV first, then paired it with the 360 V6 box.
It works well here are some tips:
After pressing the magic button to pair it with your TV and Virgin media box, press the TV icon button (button right under the TV button) this combines both the TV and STB(Virgin media box) together so they work as one single remote. This part is very important otherwise some buttons and features won't work.
Play button won't work but since the button is combined with play and pause, so press the "II" pause section of that play/pause button and it doubles up as play and pause instead.
The red standby on/off button may not work, my samsung TV has that thing where you have to hold the red power button for 2 seconds to switch it on and same again for OFF. So if you are hitting the red standby on/off button and its not working, hold it down for 2-3 secs and it may work.
Overall the URC7145 Evolve 4 remote is good enough to get around this issue, I do have some buttons not fully working like menu button on the TV but one can press TV button to 100% control the TV and then do what you need to do as normal on the all in one remote or use the learning button to assign missing buttons, then just remember to switch back to that all important TV picture icon (button under the TV button) to re-combine both the TV/STB so they work as one unit. Don't avoid doing this otherwise buttons/features wont work.
The Learning button attempts to get around the lack of some buttons not working however it does not work under the combined TV/STB mode so its a bit naff but at least you can flick back and forth if really needed doing the above.
You can buy these on Amazon for around £14-17, I got mine on clearance for a tenner on ebay.
If All in One or someone else creates a universal remote with Microphone and supports RF4CE protocol, Ill buy it and come back and let you know if it works.
