I would stay clear of any Samsung blu-ray player. I recently bought a newer model Samsung and had the exact same problem that you described. The older models have a very slow start-up time, which creates another problem entirely with the BeoSystem "giving up" on trying to detect the video signal and going into "video mute" mode until you switch to another input and then switch back. That being said, my older model Samsung blu-ray is connected to an Avant via s-video cable for the Avant and also component to the Avant for the connected Runco projector. There is only one Samsung blu-ray PUC. It's listed as "Samsung BD-P1000." If it doesn't appear, you might need a software update to update the PUC. The current Avant/BeoSystem 1 PUC has a controller for the Samsung, Sony, and Panasonic blu-ray players. There is only once PUC code for each brand. I, too, am looking for a more compatible blu-ray player. I've heard that the Panasonic has a very fast start-up time and has Netflix. Oh, one more thing, the rather cryptic "transport mode" (green beo4 button) command on the menu overlay is used to switch from using the Beo4 arrow buttons for blu-ray menu navigation to fast-forward, reverse, chapter up, and chapter down navigation through the movie. You use the red beo4 button ("PupUp Menu") to switch back to menu navigation.
The Monster HDMI switch can learn remote codes. Therefore, you can teach it to react to the Zektor switch codes sent from the BeoSystem 1. You connect an IR blaster from the AUX CONTROL port on the back of the BeoSystem 1 and place the other end of the IR blaster in front of the IR eye of the Monster switch box. You have to follow the instructions for the Monster switch to program it to learn the IR codes sent from the BeoSystem 1. Also, don't forget to select "Zector" (B&O has misspelled it) for the SWITCH under EXTERNAL SOURCES in the BS1 menu. I purchased a BeoVision 4 to connect to my BeoSystem 1 so I no longer use the HDMI.
