With my Beelink S905, I'm noticing that 23.976 videos are being output at 24.000. Had thought Beelink MiniMXIII w/LE could do 23.976?

That is probably because you are running Krypton. Fractional frame rate is not working yet on Amlogic devices with libreElec Krypton builds, although this is expected to be fixed pretty soon one of Kszaqs posts on LibreElec forum says that codesnake has released some patches that may solve this issue.

Meanwhile if your running LE Jarvis builds then fractional frame rate is working fine on Amlogic S905 devices including the Beelink MiniMxIII.

And you would be correct... I'll wait as the Artic skin I want is now only supported on Krypton. Thanks.
