EDIT: OMFG, I take it back! They work. I decided to take a VM70 and set the MK802 to 480p and it worked. I see it perfectly. So that means its most likely the cr@ppy Lilliput unit. I could just be this Lilliput is dead. I'll try the one in my car tomorrow.
EDIT EDIT: But the touch screen on the VM70 is non responsive at all, and thats testing with 2 units, both in working order. I think maybe I driver will have to be created.
