->I'm basically an artist/software person..... Anyway I need some hardware
->help.... I have this thing....it could be anything... but in this case its a
->video receiver (normal use is like to watch movies on a tv in a different
->room than your vcr....its wirelss) anyway my problem is that it runs on
->AC... 9V... and i need it to be portable... So how can I make it run on
->DC... a battery of some sort.... Is this Possible??? 
-> Basiccally I got this thing that plugs into the wall and I want to plug it
->into a battery... 

since it runs on 9VAC (from one of those funky black wall plugs??) couldn't
you just run 12VDC into it?  The polarity shouldn't matter if there's a
full-wave bridge inside the unit to rectify the AC that came from the wall
adapter, and it probably has a regulator of some sort since the 9VAC would
actually come out to be more than that DC after it gets rectified and
filtered.  You want to take this thing outside and run it and the TV on
batteries, right?
