4K USB playback broken

Up until the latest update I was playing 4K H265 files with no problem from a USB hard drive. Now after the current lot of updates playback will buffer every few seconds, totally unwatchable. I have tried high bit rate H264 files, these run without issue. Just to make sure that it is not the HDD I have copied the file onto a USB stick but the same problem arises.
Any help appreciated.

@Graham_Veness Hi,

if you’re on kernel Linux osmc-vero4k 3.14.29-68-osmc #1 (check with uname -a), wait for another update to come, soon.
Sorry for this inconvenience.

This should now be fixed if you update via My OSMC.


Just tested all seems resolved now. Harmony Companion remote now works as well.
Thanks again.
