DVD is not being detected

Hello folks,
I have a windows installer DVD which has been used by my friend for installation, and which even today is being recognised and mounted by windows.
But when I insert this dvd in in FC 11, it is not recognised, nor is it being mounted. I have tried so many things (like manually mounting using different possible file system types etc) but of no avail.
The drive is kosher - It is very graciously allowing me to use my other CDs/DVDs.

Here is one mount effort and the corresponding dmesg output:

Quote:

[root@localhost ~]# mount -t auto /dev/sr0 /mnt/cdrom
mount: you must specify the filesystem type
You have new mail in /var/spool/mail/root
[root@localhost ~]# dmesg | tail

What is happening here ? Is is really due to some sort of error.

Strange. What does this one report?

Code:

file -s /dev/sr0

The command: mount -t auto /dev/sr0 /mnt/cdrom
which was not working on this DVD till yesterday is working today, and mounting the disk as udf type partition. Till yesterday even the : mount -t udf ...
too was not working.

Sorry to have bothered you guys.

This is again bothering you guys.

I mounted this dvd as udf type file system.
The idea was to add some files to this dvd (which is a bootable dvd).
So using k3b, I make an iso image of this dvd.
Now I open this iso image in isomaster. But to my surprise the isomaster did not show any file in the image other than one README.txt.
Next I tried to mount the iso image itself (using Archiive Mounter), and here again I find that there is only one README.txt.
Naturally I was apprehensive as to where have all the files gone since the size of the iso image was 3.4 G.

To assure myself, I first created a loop device on this iso image and mounted it as an udf type file system:
losetup /dev/loop0 image.iso
mount -t udf /dev/loop0 /mnt/dvd

Now I find that the image contains all the files. AND I AM ASSURED.

But that leaves me in the dark about adding files to this iso image.

Any ideas guys ?
