• It is the speed at which data can be written onto that DVD. a 4X disc means that data can be written 4 times as fast as the actual movie is. I.e if you had a 2 hour movie,and were burning it onto a 4X disc, it would burn the disc in 1/2 an hour (1/4 of 2 hrs). If you were writing the same movie onto a 16X disc, it would take 7.5 mins (1/16 of 2hrs.) However, the speed at which it is written also depends on the computer and software. Hope this helps
