Video playback issue on High Sierra
blgentry:
I have not installed High Sierra yet. My current plan is to skip it and wait for the next major OSX version before upgrading.
I'm not sure what to advise. Maybe try reinstalling MC23? Make a library backup first, just in case. File > Library > backup library .
Maybe someone else has some better ideas.
Good luck.
Brian.

I have done some additional testing and reinstalled everything from scratch and still have JRiver hang the system when trying to play videos. I tested on an older iMac as well which I upgraded to High Sierra and it did not have the problem. The main differences are that the iMac does not used the new apple filesystem yet and it also does not have a dedicated graphics card. I see there is also a kernel log indicating a graphics card reset. I have attached some of the logs.

Can you verify that the system that's crashing has APFS?
You started with a blank disk? From what I can see the upgrade will not try to change the filesystem of the drive in a running system.

I installed High-Sierra and have no problem with video playback. All formats are playing without any problem.
May this be a problem: https://www.macrumors.com/2017/09/18/apple-files-system-no-fusion-drive-support/

However I see that on our dev system with a ssd upgrading from Sierra DID convert the running driver to APFS. It still works fine.
