When I compare it the output of the moutn command of using the first option I don't see a difference in mount options. I replied to your blog post as well, but I made an error in de code tags. Can you fix that for me?
I replied and fixed your comment's code tags. Thanks for the comment!
I'm not sure why you no longer need to specify the ISO standard. I have often wondered who it was that decided to use the .iso file extension name. It, like many things, is an ISO standard. There are thousands of standards your computer is using/adhering to. Why did the optical image get the .iso file extension name - instead of any of hundreds of other things that adhere to ISO standards?!?
