check this out, its a multi input/multi output remote switching device... each of 3 screens can play one of 4 sources independently... so one person could be watchin a DVD movie up front, while the two in the back play dreamcast... or any combination you can come up with... you could also add a VCR so you'll have 3 sources.

This is a pretty slick unit, ive put 3 of them in different viechles and the customers have loved them... and they work flawlessly!
