My 920 is running flawlessly with unstable original DreamOS 2.5 for three weeks now.
No extra skin installed.
Additional plugins that i installed:
Network browser, Dbackup, HDMI-IN plugin, MultiRC.
Am only watching fta channels and my tv is not 4K (21:9 Full HD 2560 x 1080p with 3D - i rather want 3D than 4K functioning). So i set the box output toFull-HD 1080p instead of UHD 2160p .
Got one Twin DVB-S2 FBC tuner inside. Only one cable is attached to tuner A1 which comes from a Dur-Line UK124 Unicable 2 LNB. In tuner menu, i gave 8 Unicable SNR frequencies only to tuner A1 and left tuner A2 inactive and not attached.
I don´t need a DVB-S2X (X are the ones with multistream - usually cost 30 € more than the non-X ones), because my preferred channels on Astra 19.2 don´t broadcast multistream.
(
Somebody on dreamboard compared the new Twin DVB-S2 FBC with the Twin DVB-S2X FBC tuner and wrote: both look the same, behave the same and if you don´t need multistream you can chose the nonX version.)
Without really wanting to test the box, i once accidentally programmed six recording timers on different channels/different transponders for the same time. Watched a seventh program on top, when suddenly one message after the other popped up "Recording got started". Then i controlled my timer menu and noticed that six live recordings were running simultaneously.
No problem for the DM920.
FTP file transfers (test) afterwards to my pc over GBit LAN were ~ 7 times faster than before on my old DM8000s.
Box boots up in ~ 30 seconds, so i can keep it in standby (instead of idle before with my DM8000s): Timer recordings work flawlessly from standby.
Tested HDMI-IN recording, too.
Worked okay in 1080p, but i wasn´t too satisfied with the picture quality. (Bit too bright / low contrast) Maybe need new hardware could improve this (better HDMI 2.0 cables / better 4K HDMI splitter). Don´t know yet, if i will use that feature. (Don´t want to start collecting movies and not having enough time to watch.
)
Picture quality on DVB channels is crystal clear, though, - not only on the few UHD channels.
Upscaling to 1080p lets even older 576i channels look good.
I replaced both my 8000s with one 920 and it outgoes them.
Nice box.
