	No...  TRANS.TBL is an older "translation table" scheme.  I have yet
to find anything that uses it to transparently translate 8.3 names to long
file names.  RockRidge uses the Supplimental Records on the CD in a
standardized method to provide long file names for objects on the CD.
Windows 95 / NT do no support RockRidge.  They do support Joliet, which
uses a supplimental catalog for Windows related long file names and
access control attributes.  RockRidge and Joliet (and TRANS.TBL) can
all co-exist on the same CD since the use different, non-conflicting
methods to store their information.  Their are SOME versions of Unix
(specifically recent versions of Linux) which support and read Joliet
extensions, if present.  There are some version of HP/UX which STILL
DON'T support RockRidge.  When I cut CD's, I make sure that they have
all three (RockRidge, Joliet, and TRANS.TBL) on the CD's.  That way
Windows95/WindowsNT can see and read long file names, most Unix systems
can see long file names whether they support Joliet or not, and a translation
table is present even if nothing else is supported...

	Point to note...  I use the latest version mkisofs under Linux
for doing this.  I cut product/production CD's for mastering and pressing
as well as preparation of "once-off's" and short runs.

	I'm not aware of any RockRidge support under any Windows related
file system drivers.  I could be wrong.  I hope I'm wrong.  But this was
one of those deliberate, "let's break everyone else so it looks like
THEIR compatibility sucks", moves on Microsoft's part.
