Apologies for the delay in replying Keith.
Yes and no is the short answer, most functions worked with the Beo5 although this was my first use after dealer programming. The Beo5 is now back with the dealer making minor adjustments, but overall it was functoning ok, although it was "very sensitive" on some commands. By that I mean just touching the centre select button often generated 2 command steps on the Sky + box.
Now that I am just back using the Beo4 some functions no longer control the Sky+ box in the same way, for example from the EPG Go and Red only sets a reminder for the programme and I cannot now set a programme to record from the EPG screen.
Overall something has definately changed as I can no longer control the Sky + box in the same way. I have tried rebooting the Sky + box and also some of the commands available in the Services menu that allow you to "delete and rebuild" the planner menu of recorded programmes. That deletes the entire menu of recorded previoulsy programmes, but that has made no difference.
My dealer also advised clearing the Avant of error logs (I'm not sure of the exact term / function) by entering a hidden service menu from the Setup screen, again, made no difference.
It's a mystery!
