Hello Jared! Your project sounds easy at first sight, however I can tell you that there's more here than meets the eye. I have authorized tens of thousands of DVDs in the last 10 years, as I worked as videographer for a renowned cruising line so I hope this would give me the leading edge over the rest of the bidders. I am using the whole Adobe Suite and for your specific project the Adobe Encore app would be extensively used, as it's the industry standard. An ISO file is basically an archive file of an optical disc, so upon authorizing with Encore (which automatically would create the required AUDIO_TS and VIDEO_TS folders), a CD/DVD burning software will have to be used to mock-up the burning of these folders on the hard-drive (instead of an actual DVD). I'll be using Nero suite for this task. Apparently you want to profit upon the sales of this DVD, so I warmly recommend you to encode your movie in various formats for various platforms (iPhone, iPad, Blu-Ray etc), this way you can address to a larger audience. You will also need some chapter markers added to your movie, as well as a DVD menu, so the final product looks indeed professional. I am looking forward to work with you and even if not, don't hesitate to ask me more about DVD authorizing, as I will gladly respond!
Thank you for considering my bid!
Alex
