When a DVD Image file is good and complete VIDEO_TS folder [VOB, IFO,and BUP] is recognized by DVD-Shrink easily and the steps to follow are very simple. The problem begins when DVD-Shrink do not recognize the file format, the file is corrupted or the VIDEO_TS is missing a part(s). Some times the Half Good file can be re-use and save. The ISO it can be mounted-on to DVD-Shrink using Demons Tools, VirtualClone Drive like some people suggested before or use the Double Click way. In my case the file still was not recognized by DVD-Shrink after all., but the back-up DVD file it was playable on 1 PC but not on others PC's, and not playable on any DVD Players. I re-run the Half Good File with DVD-Fab and after I did that: DVD-Shrink finally recognize the file with not problem what so ever. Re-ripping the file with DVD-Fab it re-build the file structure the right way and this way I save my "Half Good File" NOTE: The original file was extracted for the first time using a diff. Ripper (decrypt) program and with a diff. PC.
