op, you have my respect!
i have just been trying to figure out how to get composite IN on a 7" dvd player monitor i have. it comes with two screens, a master and slave. the slave is easy of course, because it has composite input from the master. works great.
the master only has composite out though. so i have been reading datasheets on the video chip to see if i can hack in an input, but i just cant figure it out. it should be easy because i could use the dvd player input, as i the dvd laser is junk anyway. that would mean i wouldnt even need to signal a switch to the new input. and since its not RGB or digital i dont see why its so hard!
GREAT work, my man.
