Need help making a data DVD ISO

First off, I'm new to linux. I've been using Windows for 12 years and would consider myself a power user. I jumped ship to linux knowing I'd NEVER be able to afford Vista and this was a good a time as any.

I'm running Ubuntu 6.10, and I prefer to make ISO backups of all my data cds and dvds. I search this forum extensivly on the subject of making ISOs for data dvds, an everyone has suggested using dd. My problem is, it won't make an exact copy of the dvd. The commands I use is:

sudo umount /dev/cdrom (per suggestion made on the wikipedia Dd (Unix) page)
sudo dd if=/dev/cdrom of=~/Applications/WoW.iso conv=notrunc

once dd completes and I mount the iso using:

sudo mount -o loop ~/Applications/WoW.iso /mnt/D

all files are present but 'installer.exe' Obviously the iso is useless to install from if im missing installer.exe

Btw, if anyone is curious, I'm actually able to run WoW using Crossover Office 6 Standard.

Thanks in advance,

Hmm - Perhaps I'm missing something...

but when I read through the man for mkisofs, it specifically said it was unable to communicate directly with the random access media device (cd-rom/dvd-rom) because they each use their own proprietary command set.

Even after trying:

mkisofs -o ~/Test.iso /dev/cdrom

mkisofs: Symlink /dev/cdrom ignored - continuing.

Reformatting mkisofs(8), please wait...

Is there something I'm missing?

Additional information...

After thinking about this problem in greater detail last night, I remembered something that might be of some help.

This isn't the first time I have (or atleast attempted to make, as this case may be) made an ISO from my WoW DVD. I originally made an ISO of the DVD in UltraISO on my windows box. I've had to reinstall WoW on a number of occasions on that box, and in every instance, it was a piece of cake to mount the ISO as a virtual drive and install WoW onto my windows box directly from the ISO.

However, what originally spured my trying to make a new ISO after having installed Ubuntu 6.10 was: once I had mounted the ISO on my HD using;

sudo mount -o loop /mnt/C/Applications/World\ of\ Warcraft/World\ of\ Warcraft.iso /mnt/D

this perviously perfect ISO had the issue stated above, e.g. all files present but installer.exe.

Could the ISO in fact have been dumped properly and its an issue with the mount, mounted filesystem or something else?
