no one uses picture in picture??

How many HDMI inputs the TV has? For the Beovision 7, the picture-in-picture works between HDMI 1 and 2 and 3 and 4. This is because the two adjacent HDMI sockets are selected by a simple switching IC and only one input signal goes to the video processor. HDMI 3 and 4 are also selected with a switching IC but a second input signal line goes to the processor, making PIP possible. If the Beovision 11 has 4 HDMI sockets, the device you want to be used with PIP will have to be connected to HDMI 3 or 4.  

BV11 the mk2 as I have - has 6 hdmi. 5 in a row back, and the number 6 at the top. Maybe I can try with the one at the top.

I have tried some combinations with the hdmi 6 on the top and others - nothing helped. Maybe some know a combination?

The valid combinations are described in the user manual. If you have lost yours, the B&O website should still have a downloadable copy. Good luck, Jean

I just checked, and unfortunately picture in picture doesn't work with two HDMI sources.

From page 28:

"There are some limitations when using the Picture-and-Picture (P-AND-P) function since some source combinations may not be possible. For example, you cannot watch two HDMI sources or two coded channels at the same time. When an invalid combination is selected, an on- screen message appears on the television screen."

It was possible on a Beovision 7 using the Beosystem 3 platform, but that functionality was dropped for the Beovision 11.

Thank you - what a BIG mistake on bv11. Also as far as I know BV11 also uses beosystem 3, but as you say, this seem dropped.
