I don't see any attempt to use the mount command at the command prompt to do this. That could help sort things out. I will leave out the long paths for clarity.
mount -o loop Fedora-9-Everything-i386-DVD1.iso dvd2
It would be interesting if that works because you had so much trouble using fstab. If the mount command complains that you need to specify a file system type then throw in the -t iso9660.
mount -t iso9660 -o loop Fedora-9-Everything-i386-DVD1.iso dvd2
If that doesn't work then either your loop devices aren't working or you don't have an ISO9660 driver or you don't have an ISO9660 image file. That is what I actually think is happening. I think that the image files are not valid.
In fstab I would change the trailing 1 2 to 0 0 since you never want the mount command to invoke a file system checker on these files.
