I found the downside of using “Music/Video Compilations” to stitch piecemeal videos together in DVD-Arc. You can’t add chapter markers! This is a big deal, since my customers expect to be able to skip forward or backward on their remotes to find a favorite scene, or to skip a laggy one. The only chapter markers in a “Music/Video Compilation” is the start of each next constituent file. And cutting up my source video files into pieces for each chapter is a super awkward workflow, saving no time, and creating extra coding opportunities for image degradation.
Unfortunately, this means I can’t really use this trick, which puts me back to re-exporting video into a single file. Fooey.
