I'm not sure I did understand the question correctly, but in order
to make a CD or DVD browsable on "Windows" PCs, they need to have
an ISO-9660 filesystem on it, eventually extended with the "Joilet"
(I think it is called that way) extension because ISO-9660 has
certain restrictions (8.3 filenames, directory depth, number of
files in directories etc.). In UNIX world, we have the RockRidge
extension to compensate this.

But we don't need ISO-9660 in UNIX land. One of the best file
systems (that isn't a file system in fact) for interoperability
is tar. You could, for example, use tar to put your files on a
CD or DVD (or at least use it to pre-master the content and then
use a burning application to record it).

To get such content from a DVD, you would just

	% tar xf /dev/dvd

But I think this is only possible with UNIX (BSD, Linux, Solaris).
"Windows" cannot handle this, of course.

So, for your own CD-ROM version, try to use an ISO-9660 file
system with the RockRidge extension, just like

	% mkisofs -r bla.iso sourcedir/

and then use your favourite burning application.

If the RockRidge extension cannot map the file names and directories
correctly, you can at least stick with tar:

	% tar cf bla.tar sourcedir/*

If this isn't the answer, never mind, just reform the question. :-)
