    Yes but the fix I said doesn't work for all videos, so we want to further improve it before releasing it, FW006A maybe? Shortly after FW006.

    I just watched a couple of x264 and x265 rips with high bitrate and I experienced a noticable ghosting on moveable objects and actors, everything like leaves it's trails behind and therefore loses it's sharpness when camera makes panning, especially in darker scenes - but only in Kodi and Spmc. Suprisingly, there is no ghosting in MxPlayer I rarely use for movies. The firmware is 005

    I believe it's the noise reduction feature that we are shutting down in FW006.
    It's coming this week.

    @MINIX - Ken, I hope you can take a look at one issue I've been struggling with since I got the U9 (I actually bought two).

    I have a lot of 3D movies in Full OverUnder format with resolutions generally between 1920*1600 (for 2.4:1 movies) and 1920*2160 (for 16:9 movies). All of these movies have had their headers edited so that the display resolution is correct. I am able to play these videos fine (as expected) on Kodi 17.3 running on my laptop (skylake CPU). However, on Kodi 17.3 running on the U9, the information on the header file is completely ignored meaning 3D videos (full OU) only occupy a small portion of the screen with huge vertical black bars on either side of the video. This makes it impossible to use the U9 to watch 3D movies.

    I tried to investigate what was the issue and created a thread on this forum and on Kodi's forum. Along the way I noticed another bug that might contribute to the reason why the 3D movies don't occupy the full screen on the U9. Stretching a video to 16:9 doesn't work on Kodi 17.3 with hardware hardware acceleration (mediacodec) enabled. This affects all files; not just the aforementioned type. Stretching a video to 16:9 does work on Kodi 16. Surprisingly, if I open a video on Kodi 16, stretch it to 16:9, open it again on Kodi 17.3, stretching works suddenly, until the system is rebooted. Someone on the Kodi forums suggested an explanation:

    "The AML mediacodec "forgets" to enable full stretch mode.
    As FTMC is Jarvis-based, it uses amcodec, which enables it, and it's never reset.
    To be communicated to Minix so that they (or amlogic) can enable it in their firmware."


    I hope you can look into this issue and see if something can be done about it, because watching 3D movies (at least the ones I have) is currently useless on the U9.

    For the first issue (header files getting ignored)
    Here's a 20sec sample clip of a 1920*1600 Full OU 3D video : https://www.sendspace.com/file/v4nvi4
    Here's a screenshot of how it looks (the correct way) on Kodi 17.3 running on my Windows PC : http://i.imgur.com/VgwCIea.jpg
    Here's a screenshot of how it looks on Kodi 17.3 running on the U9 : http://i.imgur.com/iopCz0k.jpg


    Fore the second issue (16:9 stretching not working)
    Just use any video that is not 16:9 and try to "stretch 16:9". You will notice nothing; the video is not getting stretched.
    Here's a video I recorded demonstrating the issue : https://streamable.com/zf0tv

    @MINIX - Ken, have you been able to download the file or should I upload to some other web server?

    I watched your demonstration choosing 16:9 on an already 16:9 formatted movie should have no change. A full screen can convert to 16:9. a 4:3 can convert to 16:9.
    I sampled several 16:9 formatted movies and they stretch fine unless I choose 16:9. I can stretch to full screen, but lose some video, because of the stretch.
    It appears you are trying to change to stretch 16:9 when the source is already 16:9.
