I'm trying to back up Marie Antoinette (for my wife) I ripped it to hard drive using any dvd. the total files are 4.72 GB so I don't think it should be too large, but when I try to open file with Shrink DVD I get an error message. It says ... failed to open file "I:\VIDEO_TS.IFO".the system cannot find the file specified. Any idea what'sgoing on here???
