If it's similar to the BeoSystem 3, you probably need to go into the "menu" settings (perhaps pressing "menu" twice?) to see the setup of your connected devices. In that menu system, you can see what devices are available to you in the PUC. The PUC items depend entirely on what your dealer programmed for you based on the needs you discussed. For my BeoSystem 3, I planned ahead by having my dealer program quite a few brands of blu-ray players and tvs into the PUC just in case I would ever need them. Chances are that your dealer probably only programmed into the PUC would you said you would need. Your dealer can always program more devices into your PUC...usually for a fee, though.
BTW, this blu-ray player has a brushed aluminum top that fits in really well with the B&O look. The front panel is touch-sensitive, and it has a slot-loading disc feature instead of a disc tray. With the dual HDMI, you could probably add an external tv for 3D viewing. The prices have come down considerably so that they are quite inexpensive. I recently got a 64" Samsung 3D screen for $2400 USD. This blu-ray player has an option in the settings to send the video signal through both HDMI outputs as well so you could receive the video signal through both your BV 8 and an external screen. However, if you're not planning on using it for 3D, there are much cheaper Samsung blu-ray players out there that do the same thing. There is one that is very thin, brushed aluminum, and wall-mountable, but it does not have the dual HDMI outputs.
