Now we can become Hi Grant, I should have guessed you'd be on top of this subject given your pointer a month ago about Handbrake. (Which has been a really great program.) Thanks for that and thanks for the additional info. So for my continued education, if I take an encrypted movie I can use program XYZ (Linux or Windows-based...) to create an iso image, but that iso image won't, even if it does include all the special features, ever be a bit-for-bit copy of the original. It's now unencrypted and created anew. It's a completely different way to represent the original data. That said, if it's a _complete_ representation of the original then the special features are there, and if written to a DVD _might_ work in my DVD player, assuming the DVD player isn't specifically looking for something that was on the original disc such as specifically encrypted blocks of data, etc. Am I getting closer? Thanks, Mark
