I'm flummoxed !
I did a lot of searching and could not find anything except - From Q&A - You can burn folders using Cyberlink DVD Copy. That is a separate pay for program. I would image the same is true for an ISO file.
A lot of people (including me) make ISO files or folder sets so they can easily make multiple copies for different family members. I would hope that Cyberlink would have recognized that and included that functionality in Power DVD.
I hope that I'm missing something and that someone more knowledgeable would step in here.
It is strange that none of the frequesnt posters have replied to this post about that functionality in Power Director 10.
