Question

What is the difference with finalizing and non finalizing discs?

Answer 1

not finalising a disc means that you can still write/record on it using the same machine that you recorded from, it will not play on a dvd player though

finalising a disc will end it, and you cant write/record anythink else to the disc and it can then be played in a DVD player.

Answer 2

When a disk has been finalized it is not possible to write any more data to the disk.
