Include first frame (0.00): Some authoring engines require a chapter marker to be placed at the beginning fo the file. If so, check this option. The VideoReDo's own authoring engine ignores this parameter.
So you're saying it doesn't work? Chapters may not work at all in the joiner. I hadn't actually tested it when I suggested it, just thought it should work. I'll put this on the requested feature list and check it out when I get time.
