I'm sorry - I really don't understand what you are saying. 

just read the manual! espesially p21. Be sure this is set correctly. 

OK, I'll try this this evening. Thanks

if you go into the system monitor information and it says you are in option 2 and you still have no access to audio commands then it's time for your BS3 to see service one would believe. Especially, since it is not reacting to your Opt. commands via IR blinks.

Everything is correct here - but then I never had a problem with the DVD!

Yes - looks like it. Hope they can give me a loaner while it is away....

BTW, it is the BCenter2 that isn't reacting to V.Opt - It reacts fine to the A.Opt command.  I have no idea what the Beosystem 3 is up to as I have the IR connected only via the 3.5mm jack (a hangover for when I had a Beosystem 2), so I don't get a flashing light on the sensor. There doesn't seem to be any option programming for Audio for the Beosystem 3 anyway.

Fantastic!

After idly setting then unsetting the V.Opt options for the Beosystem 3 a few times,  it has now sprung into life! I'll be VERY keen not to change much for quite a while!

Thanks all for your suggestions - I guess I'll have to put this down to B&O foibles.....
