Hi everyone,
I’ve switch to a new NAS system, Synology DS923+ and I’m having trouble playing 10 bit MKV files. The color turns grey and it skips.
I have the latest AppleTV 4K A2843, Synology DS923+ latest firmware and use SMB (I’ve also tried NFS without luck…).
Does anyone know what settings I could check?
Thanks in advance!
Jeff
What version number of Infuse?
Could you run one of the videos that causes problems through mediainfo and post the results here?
As of today Infuse Pro 7.6.3 (4619)
I’m sorry but I don’t know how to run in through mediainfo, is this in the settings of Infuse?
Or is this the speedtest?
Mediainfo is a free/lowcost app that gives the details on video files. You can get it here
or from the Apple app store for 99 cents.

Hi NC_Bullseye,
Was this the right information? I’ve edited is because at first i provided the information of the file saved on my iMac, the new info is from the one on the Synology DS923+ (but it is the same file).
Please let me know if you need anymore info.
Thanks in advance!
Check the cable. How many veins? 4 or 8 ? Perhaps the patch cord is badly compressed. Do you have the ability to measure the speed of the cable itself? Judging by the speed test above, your cable outputs 100 megabits.
Thanks for your reply!
I’ve tested a file on my NAS (wired) but opened it on my iMac with the program, my iMac is wireless could this be the difference?
When I get home I could use a windows laptop wired.
Of course there may be a difference.
There may be interference, obstacles in the way of the WiFi signal.
It may be that your Mac is connected to a 2.4GHz network instead of 5.
i’ve just got a cable tester from a colleague, cable seems to be okay.
i have 2x 5port gigabit switches.
Btw the screenshot above is from the AppleTV, not from my iMac.
Only the text provided from Mediainfo is a test from NAS to iMac.
ps. sorry for my english, i’m dutch : )
*Update
I just found out a speedtest on my AppleTV 4k 2022 wired is about 100mbps, but wireless it’s suddenly times 5…
Now i’ve found a few posts of people saying they are experiencing the same thing but no solution yet.
I’ve set-up my AppleTV wireless now but the 10bit movies are still grey and stuttering…
Also the AppleTV in de living room (AppleTV4k 2nd) is doing fine with the cable speedtest around 500.
And the 10bit movies show the same problem so this doesn’t seem to be the solution unfortunately.
Is frame rate and dynamic range matching enabled in Apple TV 4K settings ?
Sounds like you either have an old Ethernet cat5 or earlier cable or cat5 or earlier switch/router stuck somewhere in the loop. Another possibility is a weak newer cat cable. I had a cat 5E cable that would max out at about 30Mbps. Guess where it was when I found it… (Hint connected to a device with the initials ATV 
) Changed it and all was well.
The WiFi speed isn’t surprising, the newer levels are fast as long as you don’t get caught with the interference gremlins. One misplaced metal item near a device can cause havoc.
You could have poorly encoded movies. There were past posts of people having issues with 1080p 10bit videos…
Thanks everyone! This ticket can be closed.
I have found a workaround, if I transfer a file from my MacBook to the NAS everything is fine, but when I transfer it from my iMac to the NAS it gets corrupted (both SMB) so there seems to be a problem with my iMac…
For now I will start copying files from my MacBook until I find out what’s causing the problem on my iMac.
Kind regards,
Jeff
There is a known problem when copying files on M-series chips. Try copying files using a third-party file manager. No need to copy files using Finder.
For example Commander One.
Thanks will try!
