Is working almost perfect!
On Hydrogen is impressive, on Lume you have to find a good spot to watch and usually doesn’t look as good as on Hydrogen, even with the same video.
The only con I found is the screen locks because inactivity, and the navigation buttons should be hidden to use all screen (usually videos are 16:9 so navigation buttons makes the video smaller on the 16:9 screen of Hydrogen but not on the 16:10 of Lume)
