I've seen those manual switches that can have multiple systems hooked up to a single RCA input on a tv (ie the Pelican brand game system selector). I was wondering, what happens if you simply connect multiple systems without a selector and have them all turned on at one time. I know with my DVD and VCR, both plugged into one input on the tv, the picture is simply scrambled when both are on... does it damage the tv at all? Is there any type of multiple system selector which either has a remote or somehow doesn't have a selector? (i'm planning on having it out of view so that the cords aren't all hanging out of the box, reason why I don't want a manual selector). Any advice would help, is manual selector is the way I have to go so be it... Thanks in advance!
