Just a note of caution to those who use their Zidoo for MKV playback. There have been many posts regarding MKV playback issues with v2.3.*.* which to be perfectly honest is not something as Zidoo owners we're used to. The last playback issue I had was back in 2018 with v2.1.30, which was resolved with v2.1.40. Initially you have to take such reports with a pinch of salt but there are just too many users posting about problems to ignore it. I initially presumed that this was a flaw that was introduced with the dot release from 2.2.*.* to 2.3.*.* but having spent a day or so troubleshooting MKV audio and video glitches with a fellow member on AVS, it seems that the issue may have occurred in the dot dot jump from v2.2.96 to v2.2.97. v2.2.97 hasn't been released into the wild as far as I know, but it seems that recent boxes have been delivered pre-loaded with v2.2.97 and this version and beyond seem to exhibit audio and video drops with MKV playback. I'm sure some users will have had no issues with these later versions, but given the stability proven by v2.2.96 so far, my sincere advice is to stick there until this issue is resolved.
