Need some help in deciding if it would be wise to use double layer DVD's for compressing and burning, or use single layer DVD's. I know with double layer, I can get the whole movie on the disc and they cost a lot more. Where single layer, I normally would do movie only and main menu using CloneDVD and not going under 60%. If it goes under 60%, then I would split the movie. And single layer cost half of what double layer is. Any advice would be appreciated.
