It is my understanding that the rear screen entertainment system on the X5 MK1 (what vehicle do you have?) was a stand alone system. Here are the connections available at the TV tuner.

The AV-OUT connector in the rear seating area goes to the same connections on the TV tuner that Bryan showed you.

The system works as follows:

AV-OUT delivers only the TV picture from the TV tuner (or anything connected to AV-IN on the TV tuner). It does NOT show the nav screen or radio control menus (unless you have the special 760iL TV tuner, but you won't in the X5) or the reverse cam picture.

The reason is: the AV OUT was designed for the entertainment system for the rear seat passengers, and they can control the AV device connected to AV-IN (in those old days, a video recorder) which now could be an iPod or MP4 movie player.

The original BMW system used headphones for the rear seat, which were also driver from the AV connections.
The Audio on AV-OUT is a constant level line-out audio, so the screen needs a volume control.

The AV-OUT remains on the Television channel regardless of what the front screen is displaying, so you can have front passengers listening to radio or CD and watching nav, while rear passengers watch the TV and listen on their headphones.

It works really well.

Thats a grounding issue

The AV-IN has an isolated ground, to avoid ground loops.

You need to ground the DVD player to the chassis of the vehicle.

What do you mean by "cut of the bk" ??

When connecting AV-IN, make sure you connect video and video-gnd to the correct wires.

Remember the isolated video ground issue

Your posts are unclear as to what you are trying to do.

Do fix a rolling picture problem:
a) make sure monitor is set to same standard as video source (PAL, SECAM, NTSC etc)
b) make sure video input is grounded properly as AV-IN is isolated ground

Wow, OP please try to type clearly. We can't try to help you if we can't understand what you are writing.

As Kiwi says, use properly assembled cables and check for PAL/NTSC support to cure flickering. No idea what the rest of the post is about.
