That seems to be mostly solved with high speed links and better encoding technology.

I think youtube is the only streaming service that does it very well without any issues for the end-user, anywhere in the world. Mostly because of their free peering service that is extremely ubiquitous. https://peering.google.com/#/
For example, there were noticeable quality differences between MP3 coders.
Different encoders and standards will have different problematic scenarios. It seems like the number of problematic scenarios is decreasing.
I can encode DVD video (MPEG2) as h.264 at a huge bitrate decrease with no apparent quality loss.
Certainly streaming real time is harder with digital formats, but it’s generally good enough.
