I found out that "genisoimage" that ships with Debian (forked from mkisofs) is buggy, and that the original program is better, found in Joerg Schilling's cdrtools.
I was trying to make an iso file from dvd files and when I checked the finished iso, the VIDEO_TS folder was all lower-case - no good for DVD players I thought!
There's a lot of tools there...
get it from sourceforge.net/projects/cdrtools/files/alpha/
unpack and in the top dir just run..
the binaries are installed to /opt/schily/
then, to add /opt/schily/bin/ to your PATH, add this to end of your ~/.bashrc file..
or add it to an existing export line like..
test your path (restart the bash terminal)..
to add /opt/schilly/share/man/ to MANPATH (so that you can hit "man cdrecord" or "man mkisofs" etc - or run xmanand
then find the man page you want)
put this in your bash.rc file..
create iso from dvd files
or like this when in the dir containing the VIDEO_TS dir
(all necessary dvd files, VOB, bup and ifo must be present.
more coming up!
