i bet they used two 25gb discs . also they just wanted to put in a bonus disc. many companys do that .iamanoobkillme

I know that many companies like to say "bonus disc included" but I am saying that I would rather have all 4 die hard movies on 1 disc with a menu screen at the beginning of the blu-ray that allows me to select which of the 4 movies i would like to watch so that i dont have to change blu-rays ever time. same as the narnia extras, i would like it all to be on one 50gb blu-ray rather than 2 25gb blu-rays

[QUOTE="Calmed_Fury"]Why are Blu-ray movies being released on two discs? A blu-ray disc can hold 25gb (50gb if dual layered) while a dvd can only hold 5gb (10gb if dual layered). So it makes sense for dvds to come on 2 or more discs in a special edition, but why do blu-ray movies have to? I keep seeing this Narnia commercial for a 2 Blu-ray disc set BUT WHY????????? There is NO reason for it to be on 2 blu-rays when it could be on one!!!!!!!!!!!!!! Anyone else notice this or have any idea why they do this? iamanoobkillme

dvds hold 4.7 on the first layer all together it has 8.5gbs .

thanks for the exact numbers i was just ballparking it

Disney tries to make the picture look the best (which takes up a ton of space).

darthogre

how much space is (a ton of space)?

Because the video is High Definition :| HD video files are much larger than SD. Of course if they released a non-HD movie, then everything would be on one disc.Rob_101

well does it really take up 5 times the amount of space a sd movie had to use? and they come out with classic movies on blu-ray why does it have to come on a bunch of discs? for exampe ( http://www.amazon.com/Die-Hard-Collection-Vengeance-Blu-ray/dp/B000W4HIY0/ref=sr_1_3?ie=UTF8&s=dvd&qid=1210594080&sr=1-3) the die hard collection can be purchased on blu-ray but cant all of the movies fit onto one disc since they were originally made in sd?
