Only black/white image at Video IN….

Hi… I’ve been using the Video-Breakin-Box for the video display on the Volvo RTI-TFT from Volvotech.eu for some time now. Link: Link to the Video-Breakin-Box Runs great with my return camera. Now I wanted to connect to the free 2nd video input a small multimedia player with TV-Out. Have mine from England, here the link to another auction… same part: Link: Link to the Card-TV-Player The part has a CVBS(Composite Video Broadcast Signal) output. The Video-Breakin-Box has a Comp RCA input (RCA=Cinch). So should be compatible. The picture is also nicely sharp.. only it remains black-and-white!! In the system menu I have already put the signal type on PAL. NTSC does not show any image. Further image changing settings (except color adjustments, Saturation etc) there is no problem. if someone asks about it. the black/white image does not result in the color control… So what can switch the device in between?
