Format : VC-1

VC-1 is always sw decoded and can be problematic . Looks like I need to poke around to see if there might be a better decoder for it.

I know Infuse5 did some work on improving VC-1 playback. Unfortunately, they are close source code.

Not really, your Mac has much more CPU horsepower than the arm A8 in the AppleTV4.

i have the file on my NAS. i tell infuse to play it and it does. the same file plays badly in mrmc.

is this transcoding?

release notes say, "- fixed, vc1 playback on some flavors.", this does not mean all or the note would have said it.

Sorry to see you go.
