Sorry for the delay- just back from Church to see whether the Good Lord might help.
I fear no change after trying your suggestion. I do not understand these things but is it possible the SKY remote has packed up? I replaced the batteries. (I have a SKY yearly maintenance policy)
I do not often use DVDs but I made this work satisfactorily- so a picture is shown.
Over to you.
I will do that. You have tried hard to help- thank you
