Unable to read a 1 GB VOB file from DVD

[Guest]

I posted this on the general discussion board where Bob I. was able to give
me some information. However, I haven't been able to solve the problem, so I
am trying here.

I am unable to read, play or copy a VOB file that is exactly 1 GB (1,048,576
KB) even though I can see it when I explore the disk. Is there a limit to
the size of the VOB file that can be read from a DVD using a DVD-ROM drive in
Windows 2000? Playing in WinDVD gives me an error message saying that the
file has an invalid format. I can see the file under Windows Explorer and
can run a virus scan on it, but when tried to copy and paste it to my HD, but
the error message says that the file or directory is corrupted and
unreadable. The rest of the disk plays fine on my laptop and it plays
entirely on other computers (including the 1 GB VOB file). I have a Toshiba
SD-C2502 DVD-ROM/CD drive on a PIII 1.1 GHz laptop with 512 MB RAM that has
worked fine (the drive and laptop) so far.

I understand that VOB = 1GB Max, which is the size of the VOB file I am
trying to read, then why is it not being fully recognized in my Windows 2000
machine? I can't find any new drivers either for the DVD-ROM drive. The
manufacturer simply refers me to the Windows 2000 driver.

I used the Administrative Tools and checked the media pools under removable
storage and only found the following three listed: Iomega Zip (since I
occassionally use an external zip drive), Removable media (for a digital
camera that I occassionally hook up) and CD-ROM. I tried changing the CD-ROM
to a DVD-ROM 1 sided, but I get the following message when I do so: "The
media pool identifier does not represent a valid media pool." Under the
CD-ROM multimedia components, the inserted media and drive are listed as
CD-ROM (with the DVD in the drive). How do I get it to recognize this as
being a DVD-ROM and not a CD-ROM?

Oh, and I do have a CD-R drive that works fine with a driver from Windows
2000 and Roxio 5.3.5.17. The HD is formatted as a FAT32 volume, but that
shouldn't matter, should it?

Any help would be much appreciated. Thanks!

I neglected to mention that the OS is Windows 2000 Professional SP4.

What software are you using to create fhe disc / file, or what is the disc?

Actually the max size is 1Gb - 1 block.

Most likely the software you are using is generating a corrupt allocation
descriptor in the file system - some DVD movies shipped with this problem.

If you go here http://www.hitech-projects.com/udf/download.html there is a
UDF format verifier. It will tell you if the format is legal or not.

Hi, Tom.

(re-posting - didn't like URL?)

FYI: The URL in your first message worked just fine when I clicked on it.
I'm running OE6 in WinXP x64 (6.00.3790.1830), same as you, apparently.
