Viewer for DNxHR HQX files I'm using Avid DNxHR HQX as an intermediate codec to go from Resolve to Premiere, but I can't find a viewer that will play it. 

MPC-HC, MPC-BE, MPDN, Windows Media Player even the dreaded quicktime player all refuse to play it. The only thing that works is ffplay.

Anyone know of a player that can handle this codec yet?
Here is the link to the White Paper on the codec.
