I have home theater MCD183. I'm using video component (red, blue, green) cable to connect to TV. I can watch a DVD OK, but when I try to watch a video from USB the screen is blank and I only hear the audio from the video.

Then I tried to use a normal video (yellow) cable but using this I see a video distorsion (image move up and down constantly and it in black and white)

I would like to know what the problem is.
