You have a great opportunity that I do not have. If you have dual mounted LCD's in each head rest ... I would ask for TWO separate RCA connections ( one for each TV .... that would give you the opportunity to use a bag VCR of DVD player (DC to AC converter) and your could plug in DVD, CD, VCR, (RCA jack video games, playstation, game cube, nintendo ... ) into either or both video screens. You already have a lot of flexability built into your system if you have two video screens. I would keep in mind cable connected headsets for back seat viewing whether it be dual simultaneous or different shows.
