I may be wrong, but I don't think you can.

I use a Logitech Harmony 555 to control everything from one remote. Works well with all of my oddball equipment. Even works with my old Beosystem 5000, which only very few universal remotes can! I haven't yet had a look to see if it'll do the Beosystem 3000 though, but that's packed away in storage at the moment.

Quality of the remote isn't bad, but it's no B&O.

Lintronic maybe?

Thanks, I want to try and keep the B&O remote if I can I've heard of Lintronic but to be honest I was baffled by their website so didn't look any further. I might contact them and see what they recommend.

I have the Lintronic converter at home and it's great!

It translates B&O IR commands to non B&O commands but it requires software configuration.

I used the "magic box" TT455 RT238. It is stated that it works with Beo 4 and Beo 5 without problems. Perhaps you should ask before bying if the Beo 1000 is supported, too.

The box is as small as a cigarette box.

I used it to "copy" my remote controls and generate XML-files for my Beo 5. Now I can control everything(!) that uses an ir-remote with my Beo 5! :-)

That's good advice, Thanks. Maybe a Beo 4 or 5 is the way to go anyway.
