[newbie] OT: cd createing

[Goldenpi]

I have been createing cds, for use on both windows and linux, containing
programing stuff. I have created it all on my hdd, but when I try to put it
on the cd it I am given the choice between iso9660 and some filesystem
called jouliet(I think). What is this filesystem, how well supported is it,
and which should I use. If I use iso9660 I would have to do a lot of
reorganiseing directorys.
