Hmmm... VOB's without IFO's are no good. You can't open them in IFOedit because IFOedit doesn't open VOB files, only IFO files. Sorry but it looks like you have no choice but to re-author. If I was in your shoes, I would: 1. demux all the video and audio streams from the VOB's with Vobrator or DVD2AVI 2. use those as the sources for re-authoring in SpruceUP, Maestro or Scenarist or if you have no choice... ULead, MyDVD or DVDit (yuk!) Although DVDit is OK for simple projects provided your audio streams are not Dolby Digital 5.1
