Shot and edited video, created simple imovie. Burned to DVD. (had to erase tons from macbook), deleted from mac. Copied the dvd to the freshly clean macbook... Folder comes opens with audio_ts and video_ts Nothing in audio folder video folder has files ts.bup, ifo, vob extensions... What do I need to do to open the files, which app, etc? I basically need to reload this footage into imovie for for more editing. Thank you!
