i've got three lcds and am buying a dvd player with only one video out. what do i need to run all three monitors with only 1 rca video out?

you will most likly need a video amplifer, it will have 1 or 2 feeds and will have 3 and up feeds out to go to your monitors you will have to give the box 12+ but they do work well i have tried it before for custmers that are cheep and do want to spend the 40 bucks but the picture is usall week.
