With the LT template, OpenELEC doesn't like changing the refresh rate to match the video and DTS-HD and TrueHD work. I've also run into the problem where I will reboot the VM and all the settings for Kodi are reset (skin, weather addon, etc.).
With a generic OpenELEC VM, OpenELEC changes the refresh rate fine to match the video; but DTS-HD and TrueHD do not work.
