Im trying to create a discthat can be put in the dvd player and you can see music viedos but also when you put it in thesd player (like your car) you can hear music. I have been told this is a dual layer disc, Im not sure ifthis is correct. But I have no idea how to do this or if only a professional can do this. Is any one experiance with what Im talking about, or point me in the right direction?
