Can you tell what the TV user manual says about those 5 connections? A link to the user manual at the Samsung site (please tell what page to look at) might be fine also.
Same for your Go Video VCR and your Liquid Video Home theater, but then for the available outputs, of course.
However, it might be best if you find your 3 user manuals and visit your local Best Buy or Radio Shack to ask what they can sell you.
My new Samsung 32" has only 5 AV connections on the back. a green,blue, red, white and yellow.
To connect a Go Video VCR and a Liquid Video home theater to the TV what AV connector go where????
