Hi Guys,
Sorry I havent been back on here in a while... Someone asked me how I made the copy of the Mazda DVD. Heres How, specifically, not just the abbreviated cryptic versions I posted previously... Hopes that moderators dont edit my post :

I used a DataWrite Titanium DVD+R DL disk and made 3 working copies.

I used Nero 6.6.0.13 although I'm confident that the version is not important. I also know of people having success with DVDDectypter.

There are two important factors in writing this image to a disk.

1) Write the DVD with a modified BookType. The ability to do this seems to be specific to some DVD Writers. Some Nu Tech, Plextor, RICOH, BenQ, LG, LiteON and NEC devices are known the have the ability to change the book-type of the disk being written. My Device is a Samsung TSSTCorp TS-H552U with US07 Firmware. The BookType needs to be DVD-ROM. This fools teh car into thinking that the disk is a DVD-ROM instead of the DVD-R that it is.

2) Write the disk in Disk-At-Once (DAO) mode. Other methods were unreadable in my car.

Hope this is helpful.
