DVD-9 Image File using mkisofs

[Delta2]

I get this error message in IMGBURN when trying to burn a DVD-DL :

"Optimal L1 Data Zone Start LBA: None Found! (VTS_01)

This image has not been mastered correctly for burning onto a double layer (OTP track path) disc.

None of the cells meet the "DVD Video Specification" criteria for a potential layer break position."


I wish to know how to use mkisofs command to find the optimal layer break point, in order to make a ISO suitable for DVD-DL burning

Extract the files from the image and rebuild it using Build mode.

Thanks, but can't I build that ISO using mkisofs tool, isn't that possible to make layer break points using that tool ? the reason for this is because I have a automation tool

If I have the original DVD structure (AUDIO_TS and VIDEO_TS folders), can I invoke IMGBURN by line command to burn that structure directly to DVD-DL ? If yes, what command should I give ? this is another possibility that should solve my problem

Thanks for any help

mkisofs can process DL DVDs only if they have been properly prepared for that usage. The IFOs must be modified, and mkisofs must be called with some hidden command line parameters. The burn function of PgcEdit does that, but imo it is now completely outdated, as ImgBurn can do that more easily, and it does not need to create an ISO on disc first.

ImgBurn has everything you need to call it from a batch file. Look at the ReadMe.txt file in your ImgBurn folder.
