I haven't updated in fear they messed something up. Firstly they stopped universal remotes (harmony) from directly selecting inputs which they fixed in 2 firmwares after that. Then they stopped DTS from working through my amp. They say they can't supply me with the older working firmware either. There's no changelog on their site for the new firmware either.

You can probably just download the last firmware as they haven't updated it on the site and use a usb to install
