I want 4 tv screen in my car on different

video channels. how can i get this from only one player.?

i hope those screens are not for the driver.

Well if your looking to broadcast the same thing on all 4 TV's one thing you could do is go to a electronics store and get an Audio/Video splitter the easiest thing to get is a control box meant for gaming systems were you can have multiple machines hooked up using only one set of A/V wires going back to the TV. Now it is also Possible to hook 1 IN and have 4 OUT wires, as composed to 4 IN and 1 OUT. I am assuming your hooking them up to a indash DVD player so only Video wires are nessacary, and by hooking it up this way all Tv's should be broadcast on the same channel.If your looking for all 4 on a differnt channel, there are channel splitters out there, however they should be dependent on a powersource in that case your going to have either get a powerconverter to go from the Car's DC powersupply to AC for home electronics. Not sure where you would go to get a Channel Splitter, but Radio Shack is a good first try. Hope My Knowledge was useful.
