Following the http://forums.afterdawn.com/thread_view.cfm/334154 guide, I just installed FixVTS. I can start it and the drag and drop individual VOB files FixVTX window. There are Clean and FullDVD buttons that are greyed out and not active. So when I drag and drop a directory with VIDEO_TS and AUDIO_TS subdirectories on FixVTS, nothing happens. How do I activate and use this feature.
