I've got a DVD that shows over 6 GBytes of data files in Win explorer
- any way I can copy it ??

How did they get 6 Gigs on it, and still have aDVD drive read it ?


thnx,

Dual layer DVDs can hold 9GB on a single side, 18GB on a dual sided
disc. Single layer DVDs can only hold about 4.7GB per side, the
capacity of DVD-R and DVD-/+RW discs. They haven't developed a
reliable way (or any way, perhaps) of writing to dual layer discs with
a consumer DVD-R drive yet, so to copy a larger DVD to one of these
you have to make concessions - either by recompressing it to a smaller
file, or by spanning across two discs.

There's a lot more information out there if you're interested in the
technical details of how DVDs are constructed, some of it pretty
interesting. www.google.com is your friend. :)
