It seems that the new version of HD Decrypter doesn't output anything when ISO is chosen as the backup method. I backed up the main movie of 4 new dvds and although DVDfab said the each processes completed successfully, there were no files to be found in the directory. I've been using this software for a couple years now, so I'm sure my settings are right. I also tried the clean uninstall, as recommended by StormJumper (Thanks) w/o luck. I did try changing to output type to IFO/VOB and it did work. I just prefer ISO.
Has anyone run into this?
