Hi again GeoffBeck13
Just for testing purposes, does the same thing happen if you use the remote control** function on the TVGo app?
If not then it would appear to be a faulty 360 remote.
**You can control your Virgin TV 360 box from your device with the TV Go app. Here’s how:
On an android mobile or tablet:
Click on the TV/remote icon to the left of the search looking glass, and Connect to the 360 set top box. Then click on the remote control icon.
I can't check how that works on an ios device at present, but according to <this page>
You can also control the 360 using TVGo via a web browser on a computer virgintvgo.virginmedia.com
