You kindly replied to me on 28 Dec and since then I have tried all that you
suggested but to no avail.
I now find however that if I open Windows Media Player and then insert a
disc into drive D it will autoplay in that program, it will not do so if no
program has been opened prior to insertion.
Likewise if I open Power DVD and then insert a disc it will autoplay in that
program.
Any ideas on how to proceed further?
Thank you.
