I have a 22 GB .DV file that I am splitting in two and making two dvds out of. The mac dvd and video editing tools are nice, but very feature limited. The problem I am having is that when I try to import the file into iMovie to insert chapter markers is it fails with error -40. Same if I convert the file into .mov format. iDVD does not allow me to make a dvd with a text menu, so I need to add some chapter markers to split these big files up and create a text menu with another program. Any advice on a tool that will allow me to do so? Appreciate any pointers.
