as Annisman mentioned, MakeMKV will allow you to circumvent the DRM (Digital Rights Managment) or copyright controls on blu-ray or dvd disks.
I use it and like it - do not fall into the trap of buying DVDFAB - it is the biggest crapware fraud - it will work, but never work consistently, with 3 updates to correct one issue and introducing 2-3 new issues. And don't get me started on their business model of charging for another pc of crapware that will allow you to do something you'd expect to be able to do with the crapware you just paid for. Go to amazon and read the reviews on DVDFab. I bought it, spent the bare minimum of $120 to be able to rip DVDs and BDs, and kept hoping it would straighten out - i threw it out, with the distinct impression whoever wrote that software had simply learned enough to rip off someone else's software but not enough on how to make it work. I kid not
there's other software, BD Clown and AnyDVD that i've been meaning to check out but between MakeMKV and Audials One, i've been happy. MakeMKV has a full use 30 day free trial before you purchase.
i also use Handbrake to reduce my file size - when i copy a Blu-ray, the actual movie file can be anywhere from 15 to 38 GB - compressing to mp4.H264 i can reduce it down to 7 to 15 GB with no noticeable quality loss.
For copying streaming video, Audials will allow you to copy whatever is playing onscreen, and has worked well for me for copying Comcast, netflix etc
One warning - it is legal for you to keep a copy of a movie you have rented or viewed on your computer, for archive or library purposes for your own use. DO NOT MAKE COPIES to send out to your friends etc - there is software code hidden in the recording that will identify who copied it, and distribution is extremely verboten.
With Audials i can generate 1916 x 1080 copies of whatever i'm viewing - problem is Netflix, comcast etc don't always generate 1080 video streams. And Audials is not as consistent in performance - occasionally i get "hiccups" in use, ie it will unexplainably quit copying a movie 1-10 minutes into the movie, and will do that 2-3 times in a row, until the 4th attempt will be successful, ie a complete un-interrupted copy of the movie.
and just remembered, there's another software program available for streaming videos called either PlayOn or PlayLater - but only offers a free trail version that allows a few minutes of video copying per movie - that was a turn off to me so i never went further.
fwiw
