Hi Emil,
A question: Have you changed the DSS-modul with the new HDMI-inputs as we can do with warranty claim? You know maybe about the issue with Dolby Vision in 50/60 fram rates
I am very satisfied with the latest software for the Eclipse (2.1.xxxx). I have NOT noticed any bugs or errors with my Apple TV 4k or my Oppo 203. So for me the Eclipse is rock solid regarding the software right now. But maybe it can depend how you have configured the Apple TV. I have automat-configured my Apple TV and have seleted that the Apple-TV source will go to standby when I change source.
My Apple TV 4K works perfect. But on the other way I have signed up for BETA-software in the Apple TV 4k. Maybe you guys use the regular software. I have already TV-OS 12.xxxx in my Apple TV.
So with the combo of the latest Eclipse software and the latest BETA-software for the Apple TV 4K everything works perfect.
Best Regards
Martin
