I am trying to backup a DVD movie by Dreamworks. I used DVD Decrypter 220.127.116.11 to rip it to my HD. It told me that it might be inserting "dummy sectors" and inserted 2 of them. I then used DVD Shrink 18.104.22.168 to try and re-author the resulting files (just want the movie) but on selecting the file directory I immediately got the following error: DVD Shrink encountered a error: invalid data in file vts_08-1.vob What do I do know? Why can't DVD Shrink handle these files. I am a novice at this and have never encountered this problem before. Any suggestions (newbie level) on how to proceed appreciated. Thanks.
