I use Nero Burning ROM (Nero Express), and think that's the best.
Nero has a toolbar where you just push the buttons, and then it's done.
When I want to make an ISO file I choose Image Recorder DVD, instead of my Sony DVD RW DWQ30 (DVD) in the begining.
For CD-ROMs or CDs, you choose 'Image Recorder CDR/RW' instead of SONY CD RW DWQ30 (CDR/RW). Then you go on the normal way.
The there will be a ISO file on your computer. And in this case, that's the one you're gonna upload for me...
To copy DVD's, I use DVDShrink first. That will shrink the DVD files from your DVD into smaller files that will fit your empty DVD. (The DVDs you buy or rent are on double size, and won't fit 4,7 G
The files will be stored on your harddisk, and you must use a burning program to burn these on an empty dvd disc.
But let me take a look on the internet to read about DVD Decrypter.
Hard to explain on english, and when I have no pictures to show about this.
