Juz got a new NEC custom built external dvd burner lately and i wanted to use dvd shrink to compress a DVD9 disc. when i click open disc, the tool bar above indicates 4464MB size and what puzzles me is that when i manually check the size of the dvd it indicates 7.7gb. So i tried to backup the dvd however there was an error saying that the disc size is too huge. what seems to be the problem here? when i tried with my normal dvd rom the toolbar indicates 7.7gb. A problem with my external dvd burner?
