Video distribution problem

I have a problem that drives me crazy for 2 weeks now and I can find a way around it.

So I want to send composite video to three elevator displays (Rasbery PIs-windows xp-half screen) and to a lobby display small window with a video grabber avi2usb. Elevator distances are coaxial ~ 90ft - lobby display cat6 ~ 200ft

I tried diffrent video sources from direcrv box to simple composite camera.



1. Composite video to powered 1x8 avi splitter to 3 elevators working fine.
2. Composite video to powered 1x8 avi splitter to 3 elevators and lobby display - Image (not good) only on lobby display and elevators blue screen.

3. Composite video to powered 1x8 avi splitter to 3 elevators and extender over cat6 elevator display blue screens
4. Directv (H24) composite Composite video to powered 1x8 avi splitter to 3 elevators and HDMI to extender, or hdmi splitter (with or without tv connected) or hdmi to avi converter ... everything causes blue screen on elevator monitors
5. If I split the cables and connect them all together (McGaiver solution) I have a really bad image on all screens and eventually blue screen on Elevators.

6. If I use different sources of video for elevators and lobby display everything works fine.



Thanks in advance
