It's worth noting that the version of Kodi that the new Firmware installs appears to be some sort of custom HiMedia version.. Make sure you uninstall whatever version of Kodi you installed with the old Firmware first.!
From the look of it HiMedia appear to be going down the route of doing way with the external player and adapting the internal one.
There is an option for Dolby TrueHD audio and if you play a 3D iso it gives you the option to play in 3D (Although it doesn't work at present and plays in side by side mode). There are also various hardware acceleration options that are specific to the chipset in the H8.. Hopefully it's a good sign of things to come..

I've also just tried out a movie with TrueHD Audio and I have to say that it works pretty dam well within the Kodi interface... DTS not so good...
