DVD Filename trunctation

I burned a DVD with a group of shorten folders on it
using Nero (UDF and ISO). I did not check the 31
character filename. When I view the disc in my machine
at home, I see the long filenames. When I look at it in
my son's computer, I see the long filenames. When I look
at it with either computer at work, I see uppercased,
truncated names (8.3). All machines are XP.

I'm assuming there is a driver for the filesystem that is
missing on my machines at work. Can anyone point me to
what I need to install to make this work?

Thanks,
Fred
