Blu-Ray and Linux

Also it's worth mentioning that with streaming services you are getting a
sub-par quality encode compared to Blu-Ray or properly made re-encodes from
torrent trackers.
I suspect this due to using the same default encoding settings for all the
content and ignoring the actual footage nuances.
While for most movies the differences are not that noticeable, there is an
occasional color distortion, smoothed grain, or bit-rate starvation, which
can deteriorate the quality to near dvd levels at times.
But that's nitpicking. Just because of the DRM alone I would avoid any
streaming services.
