Burn video DVD from VOB files
If you start out with a set of VOB files, you need to place them into a folder named VIDEO_TS
Then, you are ready to create an image file (ISO)
$ mkisofs --dvd-video -o <ISO output-file> <input-root-directory>
whereby <input-root-directory> is the path containing the VIDEO_TS directory.
Burning would be the next step
$ growisofs -dvd-compat -overburn -speed=4 -Z /dev/dvd=image.iso
It is advised to make a dry-run before attempting to burn on the actual disk by applying the option -dry-run
$ growisofs -dry-run -dvd-compat -overburn -speed=4 -Z /dev/dvd=image.iso
If the speed option is omitted, the burner will perform at maximum speed. I usually burn at half maximum to be on the safe side.
