People are legally allowed to use a ripper to make copies of dvds and blu-ray movies as long as they do not give or sell them to other people or send them anywhere over the internet. I've finished ripping all my movie collection onto a 3 TB external hard drive, using two ripping software programs.
DVDFab. They sell several programs, each program does a specific task. You can buy them individually or as a complete package.
DVD Copy (creates an ISO file)
DVD Ripper (Creates a movie file in a lot of formats)
Blu-Ray Copy (creates an ISO file)
Blu-Ray Ripper (Creates a movie file in a lot of formats)
Blu-Ray to DVD Converter
Pro: You only have to buy the programs you want. But you need to be careful because you could wind up spending more on dividual programs then you would if you just bought the complete package for a little more than $400.00 USD
Very good tech support and forums. Technicians and programmers post frequently on the forums, and moderators provide excellent advice and help learning the software.
Cons: Software can be difficult to use, I had to re-rip over 200 movies with another competitor's software due to sound-video sync problems. There are lots of complaints about this on DVDFab forums. This single problem would, in my opinion, make the software useless.
Aiseesoft Blue-ray Ripper. The same program rips both dvd and blu-ray disks. There are no options to create iso files, just movie files in any of a lot of formats.
Pro: Excellent software, I ripped over 200 dvd and blu-ray movies with no problems at all. Simple to use software, doesn't require expert knowledge of movie jargon, and sound-video sync was perfect. Finally, the program seems to rip files faster than DVDFab. A dvd takes about 10-25 minutes depending on the length of the movie, while a blu-ray about 45 minutes.
Con: No tech support or forums. I guess they think their program is simple enough to use that tech support and forums are not needed. In many ways I have to agree.
