I'm having a little dilema. I just got a portable DVD player from Minitek. I plug a cord into the AV out jack. When I plugged it into the audio-video input jacks on my tv it didn't work. But that's not my quest. I want to know how a cord which has 1 prong on 1 end and 3 on the other splits the signal. I have a red ,white,and yellow prongs on the end with colors the correspond to each jack. I want to know how if the signals go in through 1 connection how do they split and into 3 connections. Does each signal go to eachprong or do they majicaly go to certain prongs?
