Crap. No HW decoder supports it, None, zero, nappa. This means back to high powered and noisy boxes for SW decode. No thank you please.

Ok what follows is in a"box" as you wrote, and it's not HW... But still it's a quite small and silent box, thus in my case I don't care about the decoder being SW as long as it works fine. I use the Shark007 codec pack for WIndows which IMHO provide the best codecs around, with great GUI for all the different settings (and defaults that are already excellent, no real need to play around the GUI). In a bundle that won't jeopardize your system unlike other packs like K-Lite etc. And I can play any h.265 movie file in Windows Media Player as well as Media Center: it's a superb piece of "format", and Shark007 is clearly alone on top of all those "codec providers" who otherwise "ill-bundle" codecs (you can completely uninstall the pack and the system will revert to defaut settings and files, there's also a functionality from within the GUI to do so). You should try it.
