Keep in mind for example http://www.mail-archive.com/[email protected]/thrd4.html#04255. For media interoperability [under Linux], make sure files are smaller that 2GB-1. > now i my resulting file gets truncated when written to dvd+rw and i end up > with > > -rw-r--r-- 1 root root 626862 Dec 8 09:08 > lukas-2003-12-08-full.tar.bz2 > > it should have been 1.4Gig in size, aproximatly. Take for habit to include *exact* output generated by the program (well, excluding progress indicator maybe). Also complement it with dvd+rw-mediainfo output for resulting recording. Try to generate iso image separately and check it for sanity. E.g. if growisofs command line was 'growisofs -Z /dev/dvd -R -J /some/files', run 'mkisofs -R -J /some/files > image.iso' and then 'mount -o ro,loop image.iso /tmp/test'. If you fail to access files in /tmp/test, then it's mkisofs problem, something I can't really help with. > I would have imagined that growisofs takes care of media-size?
