I have aaall these folders of anime that I need to burn that are all different sizes, making me have to think out a way to make maybe 2 of them fit as perfectly as possible into a DVD. Can't there exist a problem that testes all the possible combinations and finds out the best one? You'd have options like "files in these folders mustn't be split into different DVDs" and vice versa. It'd save me a Bunch of time and I want creds! 
This ofcourse would work with any kind of media. Say you have like 100 giggs of movies in the form of 1CD, 2CD and 3CD releases, you put the 2CD+ releases in folders and badabing, you tell the program to backup the entire movie folder as optionally as possible onto DVD's and you've probably saved a bunch of money on DVDs. Please tell me such a program exists.
