In the Windows world, DVD Fab will decrypt the copy protection and then do a full copy of the DVD disc, folders and all? Whilst I realize there are some Linux DVD ripper software, like acid rip and DVD::RIP and others do any of these remove copy protection?
You have to understand that these play the video through the software being used and encodes only the video and audio parts of a DVD to a different video Format. For the question part the answer is yes.
