Thanks for your help!
I have configured my remote with V Opt 2 and A Opt 1 as recommended by B&O support.
Things have improved somewhat in that I can control DVDs now using forward/rev etc but only if I press the CD button on my Beo 4! The DVD button doesn't seem to do anything.
I don't think it's a faulty remote as I've got two Beo 4's and have the same problem with both. I'm not sure if it's a Beo 4 problem or a beocenter 2 problem.
Has anyone got any ideas?
And yes, I've got Beolab 6000s connected to the Beocenter 2.
