    I am unable to play a 4k blu-ray disc on my mid 2014 rMBP. It starts playing, but the video is very choppy. It is not view-able.

    The specs for my MBP are.. 2.8 GHz Intel Core i7 Processor. The memory is 16GB 1600 MHz DDR3. And the Graphics are NVIDIA GeForce GT 750M 2048MB Intel Iris Pro 1536 MB


    I can play small 4k clips (created by my iphone) perfectly fine, But the larger files (around 25 GBs), are just not viewable. Is it my MBP? Is it not fast enough? What could the problem be?

    BTW, I tried viewing the blu-ray with VLC and Leawo Blu ray Player

    Thank you very much for your help!

    The problem is probably in the poor support of H.265 decoding on OS X. iPhone records 4K movie also in H.264.
    Someone on this forum suggested a minimalistic MPV player for H.265 playback, and this one has been the only one that can really play back 4K H.265 encoded video on my early 2013 15" rMBP.

    2014 rMBP GPU's (iGPU or dGPU) doesn't support h265 or vp9 codecs, for this all decoding process is software not hardware decoding.

    For this reason i'll buy a 2016 rMBP.

    Does it have H.265 support in hardware?

    25GB? Even for blueray quality, that's a ton. Just run it through a converter to h.264, you should be able to get the file size down to something like 20% with no noticeable quality loss too, plus it will play fine.
