It was my understanding that it went like this (someone please correct me
if I'm wrong):
iso9660 only supports 8.3 names, and only allows 8 levels of directories.
Under UNIX, the Rock Ridge extensions are generally used to get larger
file names, etc... (I believe it's actually called RRIP - the Rock Ridge
Interchange Protocol).
Under '98, it uses the MSFT way of expanding file names (I believe it
actually stores the info in a second partition; thus the first is an
iso9660 f/s, and the second is the proprietary Joilet f/s for MSFT's
own purposes ;-)
Therefore, the strict iso9660 image will only give you 8.3 file
names, unless rock ridge is present, in which case things should work (as
long as the image/burner can burn the rock ridge extentions). I don't
know if the images you're referring to have the rock ridge extensions or
not...
Hoep this helps,
