DVD+DL movie quality backup question?

Hi all,

If I back up one of my commerial DVD films to a dual layer DVD+DL using DVDdecrypter or DVDshrink and my NEC3540 will I lose any film/picture quality at all.

Hopefully because the copy will fit the complete whole disc without compressing/shrinking - the quality should be the same.

Is this right?

if u want a perfect back up of your dl original disc…use dvd decrypter in “ISO Read” mode then burn it using “ISO Write” mode w/ dvd Decrypter. use it at 2.4x for your first try. Don’t use dvd shrink

because dvdshrink SHRINKS the disc which would reduce quality??? :confused: :confused: :confused:

DVDShrink will also rip and burn ISO files without compression, but there’s no reason to use anything but Decryptor.

Agree :iagree:
DVDShrink can do BOTH things: reduce size & burn on 4.7GB medium, OR just ripping & burn on 8.5GB medium.
I prefer DVDShrink for shrinking/ripping, DVDDecryptor for burning ISO files.
So, IMHO there is NO REASON to be afraid of DVDShrink! :slight_smile:
