I'm new to this software. I've already successfully converted two VIDEO_TS folders to dv files and imported them into iMovie, but for some reason the third folder, which has several chapters, is not converting properly. The first chapter seems to play back fine, but it's as if the other three are layered on top of each other: The video freezes on one pane for the remainder of the show and the audio seems to play all at once, very quickly. Is there something special I should be doing with the files???
