Just received my unit today. A few issues: With Roon, it will not play my multichannel files over HDMI properly. Roon keeps converting them down to 2.0. They play fine from my Roon Nucleus server over HDMI. I thought this unit was Roon Ready? And, I ripped a few movies into .iso format. One for example is Fast & Furious 9 in 4K. Zidoo will not play the .iso file at all. I have it on a hard drive which is inside the Zidoo. It sees the movie, creates a cover for it will all the info, but it won't play - just a black screen. I will try installing the latest beta firmware shortly and report if anything changes.
