Created attachment 331714 [details] VTS_12_0.BUP file that's giving problems With app-cdr/cdrtools-3.01_alpha09, mkisofs fails to calculate image size when I am backing up a particular DVD: $ mkisofs -print-size -udf -dvd-video -f dvdbackup Setting input-charset to 'UTF-8' from locale. mkisofs: Implementation botch. Video pad for file VTS_12_0.BUP is -3757166 mkisofs: Either the *.IFO file is bad or you found a mkisofs bug. With app-cdr/cdrtools-3.01_alpha08, it works correctly: $ mkisofs -print-size -udf -dvd-video -f dvdbackup Setting input-charset to 'UTF-8' from locale. Total extents scheduled to be written = 3781360 3781360 I am guessing that this is an upstream bug, but the upstream project homepage looks like it was designed in 1995 and has nothing resembling a link to a bug tracker. I am attaching the VTS_12_0.BUP file in question. The full DVD image is 7G, making it impractical to share, but I am willing to run any test code you want on it to help diagnose the problem.

You are right there is no bug tracker for the project but you can use the mailing lists [1,2] for reporting the bug which I would appreciate. [1] https://lists.berlios.de/mailman/listinfo/cdrecord-support [2] https://lists.berlios.de/mailman/listinfo/cdrecord-developers
