use DVD Shrink, it will fit it, also movie it shows as 8 gig, but in reality "productions" add some stuff there to make it 8 gig but thou the movie is less then 4 they add stuff such as extra "garbage" let me say "not videos" the only reason they add 'garabage" is because they dont want their DVD's being copied to 4gig DVD-R's etc....when the 8 gig DVD's will be released ,you will see that new Released DVD's will be 16 or more gig's in size and that will have nothign to do with the movie quality..
