I gather you read back here where Tinwarble and I tested a Hi10P, and it played back fine with HW turned off.

After that, a change was being implemented to Kodi to automatically turn HW decoding off for Hi10P.
I am playing that same 1080P Hi10p sample now on Kodi 16 nightly from the 29th, and it was fine without me having to turn HW off, so it is obviously working as it should.Actually, there were two stutters in it. CPU cores seem to sit around 30-50%, with a peak of 80%
