When building a cdrom against iso-norm the files get a 
stripe in there names ("-"). 

But my experience will say that burning that file on a 
cdrom and put it into a mac, that the following error will 
occur:

the sign "-" will be converterd to a "_" and when this 
happens the links in a website are not correct any more. 

SO: on a PC it is alright, on a mac it's not alright.
(i tried it many times but this is the problem, so i think 
the iso option in the programme is not right enough)
