What is the advantage to having a dual layer dvd burner? will it make me be able to back up some of the longer dvd's without compressing them or removing sound or menu's? Do they take different dvd's than regular burners do.
 
CD/DVD 101

DL (dual layer) is a designation associated with DVDs and denotes drives/media that are capable of burning DVDs that have multiple layers to them (4.36GB for consumer media, 8.72GB for commercially stamped media). In order to burn using "dual layer" you must have both dual-layer media as well as a dual-layer capable burner

A dual layer is almost double the capacity of a single layer dvd, DVD Movies are dual-layer.

The CD/DVD 101 should answer any of your questions.
 
I have the same questions you do. Does compression degrade the original images or data? If not or if loss is negligible, then why not compress to single layer. Can all, most or any DVD players read compressed DVD's? I scanned thru CD/DVD 101 and didn't find these answers. Maybe I missed it.

thus Dual layer only applies to DVD burners that can do it and if the DVD that is being burned can have dual layers. and dual layer offers more space.
i dont think it has to do with compressing anything.
for example its like having 2 shelves. instead of just having one you have 2 so you can add more. well thats the way i see it...

or have a look at the dvd forum provided in the 101. or you can even google dual layer to find out more.
google does wonders
 
same here, duakl layer i have never used, too expensive for the disks and not supported anywhere else, im the only one i know who has a DL drive... that and DVD-RAM, i still havent used that, again expensive disks and also the lack of compatibility among other computers is a down fall, it will be good in like a year when everyone has good drives etc...
