cMP 2010, is anyone else struggling with 4k video playback?
I have a pro with dual x5670's, 64Gb RAM 1333Mhz, macOS 10.12
Some 4k videos are playing fine, like YouTube, etc but some (not all) of my downloaded 4k videos (h264) are not playing well at all, the sound will not sync or the video is choppy, etc. It appears to be only with larger video files 20Gb plus.
Anyone else had this problem, is the hardware just too old for 4k?
I use VLC and have tried over players also.
