Sorry to resurrect this old thread, I recently got a Beovision MX 3500 second hand and a Tevion MD 83388 universal remote with it. I had a Meliconi Universal 5 Web remote as well and I am in the process to set it all up. The Tevion was set to "Bang & Olufson" mode already and I managed to set the Meliconi to "Bang Olufsen" mode
