One alternative is to purchase a consumer friendly DVD-burning application such as Roxie Toast Titanium. With that, you can export a standard video file (like H.264) out of Premiere and then drop that file into Toast, which is a consumer friendly, easy to use app for burning video files to disc. H.264 is like a 8 out of 10 in quality but Toast will definitely accept the file. ProRes or DNxHD are gonna give you slightly better quality but I’m not 100% sure Toast accepts those files. Frankly, it’s probably a moot issue because the video will be compressed to DVD quality (which isn’t great) anyway so I’d just go with the H.264 option!
