Hi all,
all this backup copys of my Subaru navi DVD are running in my car.

I used:

Programm: DVD Decrypter Version 3.5.4
Burner: Plextor PX-760A Firmware 1.02
DVD+R DL: Verbatim Printable x2.4 dey: MKM-001-00
Fujifilm x2.4 RICOHJPN-D00-01
Philips x2.4 CMC-D01-00
Samsung Pleomax x2.4 RITEK-D01-01

PC: Asus A7V133 AMD Duron 900MHz DRAM 256 MB
Windows XP Pro SP1

First i did an ISO-image on a NTSF-partition.
I used the defaults of the programm.
All named DVDs are running good.

I controlled the quality of the burning with Pextools Pro XL.
With alcohol 120% ver.1.9.2 I wasn´t able to get a running copy.
The critical point allways was the stepover from layer 1 to layer 2
and the region at the end of layer 2.
