I'm trying to create a copy of my BMW professional Nav DVD and adding in the UK speed camera database. There's a description of how to do it here on a PC. I've managed to do all the file editing and PERL script etc, but the problem comes when I try to burn it. The how-to uses Nero and creates a hybrid ISO/UDF disk using relaxed ISO restrictions to allow longer file names, but also states that the Joliet file system doesn't work. On Toast, the only option for longer file names when burning ISO is to use Joliet. I've tried burning it using just UDF but the disk was not readable by the car's system. At the moment, I'm trying to use terminal to make a hybrid from a cdr disk image. Can anyone suggest another way if this doesn't work?! Thanks in advance.
