Answer to num. 1
If you want to view movies.You will have to of course buy a dvd player.Some come with it included in the package.If you just buy the monitor and wire,you will get power,but of course,no signal to anything.

2.
Yes it can be ran off a ps2 instead of a dvd player.The wonderful thing about the ps2 is,it IS a dvd player.(Handy eh?).Usually the connections are behind the screen.(A/V or colored cables,red white yellow)

3.Not really sure about this.I had mine installled by pro's.Sorry.




4.
No,not if you dont want to.Most people just directly connect the monitor to the battery.
