Explaining Dual Layer recording

[ironlungs]

Ok so a friend of mine was telling me if you have a DVR burner capable of burning data in dual layers, then you can use a 4.7GB DVD-R and actually burn over 8GB of data...is that right? If so, does the DVD software recognize the disc as 4.7GB or 8GB?

I also heard something about being able to get 16GB off one DVD-R? Is there any truth to that? thanks.

There is +r DVD media that are 8.5GB , 4.7GB DVD's are 4.7GB, i have never Bought a DVD that was 16GB.

Edit: There is no DVD-r that is 16GB

To burn Dual layer you need a Dual layer DVD burner.

You have to use media that actually has 2 physical layers. The burner cannot just create a new layer. One of these:

so basically you need both a special burner AND a special DVD-R

You need a dual layer dl+ compatible writer and dl+ media.

Holy crap those blank DVD-r DLs are expensive. Anyone anticipate they'll drop within the next millenium?

they dropped a lot already, from 16 euro to 6 euro her in europe in a half year, so i think they will drop very slow now.

its not worth to burn data on it, when you are able to burn it on a 4,7 gig for 1 euro (if you use high quality discs).

and its not worth to copy movie dvds with it, becasue a few euros more and i can buy the original again.

i really would like to know who buys 8.5 gig for 6 euro? if nobody would buy it it would drop like hell. i will start to buy it when they cost below 3 euro, but i think this will not happen the next 10 months
