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 too.
Using the Meliconi I set up all TV channels without much hassle, but getting the PS2 to work seems to be impossible.
The PS2 has RCA out and I have adapters to S-VHS and SCART as well. Using both of the remotes I can manage to get into the menu to set the AV1/AV2 connections (they are set to V.TAPE-1 / NEW and V.TAPE-2 / NEW at the moment.) I turn on the PS2 and nothing happens, regardless which connection I have it connected to.
Since it doesn't switch on its own, I tried to find a way to force it, without success. Apparently the original remote has a VTAPE button, but I can't seem to setup my remotes to send the signal associated with that button. Is there any other way to switch to AV mode, or maybe I'm missing some other setting?
