I have a lot of quicktime movie files that I want to put on a dvd. Individually, they total more than 4.7 gigabytes but in terms of total running time they are much less than 120 minutes, which are the size allowances of the blank dvd. If I make a dvd, am I limited to the total file size of the original material I can put in it or will the dvd compress the material so that it can get up to 120 minutes of movies on one dvd? In other words, can I only put 4.7 gb of material on the dvd or can I put 120 minutes of video on the dvd? Thanks for any advice.
