theres many different types of disc's, theres dvd disc's to burn dvds and cd discs to burn mp3 or media formats, then theres information disc's that can hold alot og space for any thing you need, if you just move the files or copy them to the either disc there just read as files and can be opend to run, OR you can use a certain kind of disc that ALLOWS certain files to be burned onto it then when you pop the disc inside it runs automaticly when the files are automatilcy opend and read.
Thats my guess
its just im sure theres certain formats that arent allowed to be burned on certain disc's but only placed there not burned, theres a difference in burning and just placing files on a disc.
