Hi Matt, Thanks for responding. I havent tried anything else, just what is in T-18. I just downloaded it last night. playing with it now. I tried DVD creator, and at least 5 others. All I want is a DVD authoring with chapters buttons! Not everything works with High Sierra. Some of the software or apps don't support chapter buttons, or the capabilities to durn to a DVD only BR. Pulling my hair out! Guess I'll just have to suck it up with the lack of options and just get this done. I digitized all my dad's old home movies, imported the files into Mac, edited with dates, names,music. so the timelines are done, I just need to get the chapters in there by the year and get these suckers burned to discs. The movies start in 1956! I'm sure a lot of people are doing this sort of thing with old home movies.
