I have installed way to many of these freekin things for my own sanity, good news is bosee has real tech support with people that are trained properly to answere your quest\problms and Ill tell you if your gunna diy this thing your best bet is have that phone number ready chances are youll need it. Anyway that silly comp vid adptr dongle pos thing has made me lose lots of hair, first unless you are a pro with lots of wire management skills do not try to use thick comp vid cbls to hook up to this as it will pull itself out of its s vid input! second dont count on the color coding to be even close to right red-red green-green blue-blue if you have problems try switching the colors around other than that good luck have a few drinks and have that tech support number handy.
