Thanks for your assistance with this. Unfortunately, it hasn't really helped, as I have tried the suggestions (seeting up as Cisco, setting up as Virgin Media) and neither have solved my problem. In the end I have reverted to the settings for the Scientific Atlanta V+ remote, and this covers most controls. It just doesn't feel like the right way to go, and obviously will require learning many additional commands etc.
I have logged a query with Logitech, and will see what their response is.

Thanks again for your help
