    First speedy test with 6.0.60. Everything is the same...
    Ready Player One und Birds of Pray, stutter after a few minutes
    Maybe Reset or special setting helps?

    The bulk of fixes in this firmware were released on Monday and after a request by Zidoo I got a test file to them on Wednesday, so hopefully we'll see a fix for this next release.

    The problem with stuttering has been known for very much longer, i think at least 2 months?

    I’ve been trying to reproduce the issue but failed. Just wondering, maybe try a different HDMI cable?

    EDIT: Seems like Mark has reproduced it. Hopefully Zidoo will fix this for you guys.

    Someone said Justice league worked fine via yuescopes method

    Just tried it several different ways
    Straight makekkv .53 to mkv file Mel 7.xx profile ............................................standard stutter audio sync issues after 3 min44sec showing as DV and DA
    Yues Gamma to mkv file Mel 8.06 profile ............................................showed as mel 8.06 in mediainfo .played as hdr10 only no stutter/synch issues
    Yues Gamm to mkv Mel 8.06 but then run thru MAkemkv .53... showed as Mel 8.06 in mediainfo but standard stutter audio synch issues at same 3min44sec area showing DV and DA

    switch to non atmos track and dolby vision plays fine

    Different timestamp for the synch audio issues to Alita which was always closer to the 5 mins run time ....slide movie forward starts back all in synch ,stutters after 5 mins ish playtime again et al each time slide forward

    mediainfo for final version

    would be interesting to compare with whoevers got Justice league working ....full movie not a 30 sec snippet which doesnt show the issues

    experimental and buffer set as suggested both have been for like a week now and latest .60 patch running

    I’ve got a version of this I will try later.
    Will let you know.

    Yep, seems to be broken again with Justice League on the latest firmware, I’m still begging the question how much testing was actually done on this product?

    Could you pls provide us some samples?

    Mirror, the problem only kicks on after about 5 mins, that could be a big sample.
    Mark Swift has been able to reproduce this bug, I wonder if he could rustle something up?

    Hi, my justice league file was created with the original mp4 method with Atmos file de muxed to extra mo4 file, all with ffmpeg.
    I have recently recreated this file back into a mkv with make mkv then mkv toolbox, I doubt it is the original chapter points causing the problem in this instance.
    I personally feel the buffer is choking on this particular combination of streams.

    This is a new species. The whole thing is still an experimental phase, not just for zidoo. So I hope you will be patient.

    That's correct - you can turn HDCP off if you are only using the box for playback of local rips.

    I've already emailed links to samples of both types of files last week - 10 minute dvhe.07.06 MEL ATMOS and dvhe.08.06.
