I received a DVD which plays a movie when I put it in my DVD player with my TV. When I put the DVD in my computer I get a different menu with options. I looked at the file directories on the DVD and in addition to the AUDIO_TS and VIDEO_TS there are several data file directories with .doc files, .jpg files, etc. I have been trying to duplicate this with no success. Using Roxio 7, "Copy files to disc", doesn't work because the movie won't play. Nothing is copywritten. I can make "just" the movie DVD or "just" the data DVD but can't figure out how to combine both on one DVD like the one I received. Does anyone know how this is done????
