My sister-in-law got married and the wedding photographer made a DVD with 412 pictures. Unfortunately, my parents-in-law could not read the DVD, either with Linux (which is their main OS) nor with Windows XP. So they gave the DVD to me and I had a look.
The DVD is a DVD-R and my Linux version (Hardy Heron) tried to open
it: it showed the dialog asking if it should mount the DVD. A failure
message opened asking me to have a look at dmesg. Hmm.
So I did and it said:
[ 2981.006899] UDF-fs: No partition found (1)
[ 2981.125072] ISOFS: Unable to identify CD-ROM format.So I tried to install some kernel patches for udf.ko, but this did
not help. The disc was still not recognized. In the end I decided to
call upon the trusted program hexdump. Hexdump should be
compulsory at kindergarten!
Browsing through the data with hexdump, I quickly recognized JPEG headers, so I wrote a small program (70 lines) to extract all JPEGs from a binary blob. You can download it.
The first megabyte of the DVD is here.

I'm sorry my solution didn't
I'm sorry my solution didn't work. Although the headers look similar, your DVD seems to have an entirely different problem (I never got "no partition found", and I think mine was readable from XP).
Any idea if it is a multisession disc? More than once XP's multisession created discs that Windows itself couldn't read later. I doubt it that Vista's multisession handling is perfect, either.

works in the photo store
The DVD did work on a machine in the photo print store. No idea what OS it was running though. How can I check the sessions?

multisession
On a Windows machine with Nero, open Nero Info Tool and check the Disc Info (IIRC).
On Linux K3B is usually able to display the same information (if it manages to recognize the disc).
