Hi,
I inserted a disc into my drive and found this readme.txt on it:

====
This disc uses the UDF file system.

You are currently looking at the ISO 9660 part
of this disc.



To read the content of this disc you have to
install an UDF file system reader.

For Windows 95 please run the program 'AUTORUN.EXE'
from the root directory of this disc.
====

How can I switch to the UDF part?

Thanks, Jan

Hello Jan;

Just a guess here, but you transferred the file to a DVD. What you are
supposed to do is "Burn the image" to a DVD. Consult your DVD software for
how to do this. Also, check this website for more information about using
an unstable, incomplete operating system.

This is easy. Install Windows XP SP2 on an empty system where there is no
"Program Files", "Windows", or "Documents and Settings" directories. Look
at the DVD. Do not install any product from Nero, Roxio, or Sonic
Solutions - that also includes any CD and/or DVD creation software bundled
by HP, IBM, Compaq, Dell, etc.

Hi Mark,
thanks for the guess, but I didn't burn this CD-RW, I just wanted to read
it. I expected that when Vista can write UDF it could also read or switch to
UDF when present.

You mean I cannot read it on Vista?

Haven't tried UDF on Vista myself, but if the software on your Disc won't
run, maybe you need the latest version

Go to "http://www.roxio.com/enu/support/udf/software_updates.html"
and download the UDF reader from there. It doesn't say if it is compatible
with Vista

I was assuming this was one of the new Vista DVDs. A UDF disk created by
Roxio's or Nero's UDF driver requires the reader be installed. They both
use non-standard variations of UDF and are incompatible with Vista's for the
moment. I quit using UDF for my own CDs and DVDs as it seemed to cause more
problems than it solved.

LOL. So much for the "Universal" in UDF. Maybe Roxio and Nero should call it
PDF, for Proprietary. (Oh wait, then Adobe might sue).
