I have a Daewoo 42" monitor with Bose system for sound, VCR/DVD comb,a camera system(video 2) and Satellite system(video 1). I am having problems getting the VCR/DVD to show picture on the Daewoo monitor. I get sound but, no picture. The picture happens to be what channel I have on the Satellite at the time. How do I hookup my unit to give me the picture off my VCR/DVD and still have access to the satellite and camera system?
