No direct play MPEG4 on early access

Client Version#: 5.10.0
Platform Version#: 4
Device: Samsung smart TV

It seems that in the early access app I’m not able to direct play MKV files with MPEG4 video codec anymore.
I confirm it’s working without the early access with version:
Plex for Samsung: 5.1.0
Tizen: 4.0

Hi,
since this is now generally available, is there any fix?
