Ok so there definitely are different video pinouts. So not all 3.5mm video cables will work...if your doesnt seem to work try flippin the red and yellow cables and see if it does....Standard 3.5 to avi cables should work...(like the cheap ones from Target....only 5 bucks) but custom designed ones like for ipod or car stero ect may have a different effect. So DONT get bummbed if you try and it doesnt seem to work....devine an conquer people, try a different set and you'll see!
Here is a retractable pair for under 5 bucks......good for on the go
