Yes, I realize that. There are Plex apps for everything. But then you have to worry about your Plex server being up, people’s upstream bandwidth is usually piss poor since most people have cable. On top of that if your device doesn’t support the same format that you encoded it in, the Plex server has to transcode.
That both limits the quality and puts more load on the server limiting the number of simultaneous streams.
Not to mention when torrenting you have to troll/trawl [1] the internet for a good high quality rips.
Or just using streaming service.
Since Disney is one of the four major studios that support MoviesAnywhere, you can buy a digital movie from any of the participating stores like from Apple, Google, Vudu, Amazon and they will automatically be available in your library from the other stores.
Also you can stream Plex from anywhere these days. Even just casting from your smartphone to whatever device is very viable.
