Tested a lot of 4k rips with 10bit color and I get no audio dropouts on any color space modes.
I am not aware of markswift2003's dropout frequency, but I experienced no issues during 10-15min playback of 4K ATMOS clips (selected scenes).
BD playback seemed perfect. Pink's full concert was played from start to finish (in menu navigation mode) with no issues at all. I didn't test 1080p that much though. No MKV's at all.
Auto mode works also well. All tests were performed with "original content" setting in color space, not maximum.
Compared to zidoo z9s, UHD menu loading times are also significantly better. There were UHD backups that would refuse to play on both players in menu mode, but some played on Dune and not on Zidoo (new bad boys, dr sleep)
Image quality was exactly the same between Dune Realbox 4K and Zidoo Z9s.
All tests were on a friend's LG 65" C9 and Marantz SR7012. Tomorrow i will check some more with my setup.
Youtube app is "fine-tuned" and even though VP9 is supported, the box struggles with high bit-rate VP9 material when on 4K/60/HDR. If you select the second resolution from the top, you will not have problems. I suppose that the 1619 model will for sure perform better.
I did not install any KODI/SPMC version. I am not sure i ever will.
I made a lot of DV tests but no luck. Tested on all FW versions.
The ios app is amazing! Will test the Android equivalent (I hope there is one
First impressions exceeded my expectations. Aside from Netflix, the Realbox is better than last year's Pro 4K model.
