To get things clear.

Option 0 Audio or Video shuts down the ir-reception, nothing more.

Option 1, Each audio or video device reacts to it own commands

Option 2 This makes the video OR the audio a Master device. Video option 2, then Audio in option 0 (when linked and speakers attached to the Video device). Audio Option 2, then Video in option 0 and speakers connected to the audio device.

Option programming is done in stand by and confirmed by the flashing once by the red dot led.

Option via Beo4 => VOpt or Aopt(under Standy and List simultainiously, then config), then press optionnumber

Option BL 1000, choose ,sound, store, optionnumber, store (for audio option programming)

Option BL 1000, choose, picture, store, optionnumber, store (for video option programming) 

Putting the MX 5500 in option 0 sets the ir reception to off and so the DVD1 MKI or II, will not respond.

Thanks so much for the detailed reply. I already tried this, but it did not work. Sending the picture 1 command unfortunately did not work. On the beolink 1000, there was no effect by pressing store in between picture and "1", but picture 1 store worked. I confirmed option commands are getting in, so that option 0 did stop command receipt, and option 1 restored it. However, the led does not flash while in standby on the TV (it does on every other b and o equipment I've done option programming on). The dvd1 is connected via the scart cable to the vtape input. When i press vtape the dvd1 turns on and starts playing. However, it does not take any commands, and when I put the tv in standby, the dvd1 does not go into standby. Any thoughts?

Thank you. I tried that. While video and audio come through, when I hook up the RCA jack Datalink socket on the back of the MX on the AV2 area to the Mini mono control jack on the back of the DVD1, it prevents the MX from responding to any remote commands, even to itself (which does work with the SCART). Is there an incompatibility issue? Is there a special cable that makes this work?

You've lost me here.

Did you use the control jack on the back of the DVD1. The only use for that is for software updates.

The only way the mx commands the DVD1 is by scart. On pin 8. So try another scart cable? a fully wired. Or is it the same as used with the avant?

On the US MX5000, AV2 is not a SCART connection, it has a set of composite inputs, an SVHS input, and an RCA type connection marked Datalink. AV1 is a SCART, which is what I have been trying to make work. On the back of the US DVD1, there is a SCART jack, and a set of RGB inputs, a CONTROL jack and a SERVICE jack. The SERVICE jack is for software updates. US Avants do not have a SCART jack, so the way you connect a DVD1 to a US Avant is through the RGB connections, and a stereo mini to stereo mini plug that goes into the CONTROL jack. My DVD1 works just fine using these connections with my Avant, so I know the CONTROL jack on the DVD1 accepts commands from the Avant.

I do have another SCART cable on my way - that is what the US Beocare suggested. However, I checked continuity on pin 8 of my SCART cable, and it is correctly wired. I suspect the new cablet won't correct it however, since both times this happened with both DVD1s everything was working fine until I sent a Picture option command. I suspect the software in the MX got confused. Is there anyway to do a reset on the MX software? It still concerns me that the LED on top of the MX does not flash when it accepts option commands, like every other B&O unit I have tried does.

Thanks for all the help.

Ok, I didn't know that it is an US type, here on the other continent we have only 2 scarts and a S-VHS socket.

But I had in the past the same issue with option programming. I was told then that Picture Store 1 Store should work better then Picture 1 Store.
