I've been seeing a fair amount of posts here and on other sites that say it's too hard to rip physical discs or prep a digital source. In all honesty, that just sounds like someone trying to justify piracy. Competency in ripping a blu ray nd/or obtaining a steaming source isn't something that magically happens. It takes research (Google, forums, etc). It takes trial, error, patience and perseverance. If you're going the streaming routes, it's going to take a chunk of change upfront to buy the necessary programs to get those files. There are no free options to do so. Some of these programs are over $100 dollars. The source files produced by these programs also fluctuates between 1/4 and 1/2 quality when compared to physical Blu ray disks. There are few programs that I know of that can actually obtain 4k streams at the moment.
For context, I use iTunes for some sources. The program I use to decrypt the m4a movie files set me back around $40. It only works on older versions of iTunes too. So any program that you buy is subject to be rendered obsolete as new encryption models are developed. iTunes files are encoded at ~6mbps (~1/4 the quality of 25gb blu rays and 1/8 the quality of a 50gb Blu ray disc). You get an inferior product and inferior source file as a result. Ultimately, it's cheaper and higher quality to go physical.
