I’m having the same problem with the True HD Japanese language track on Akira. If I select it the video stops roughly every five seconds, hangs for about three then plays again. It’ll do this for the whole film.
Now if I select the English TrueHD audio track it plays just fine.
Using a 2017 Nvidia Shield tv with PMS on a dedicated PC hardwired.
I’ll edit this later on with version numbers but I’m pretty sure they’re current. And I’ll try to add a log file from it too.
