I’m using Plex DVR to record to my HDHomerun Extend. Several months ago, the Plex DVR use to transcode directly to .MKV now only .TS. How do I get this feature back to have Plex DVR produce a .MKV file while recording?
I think this stopped in July 2017.

(DVR) Use MPEGTS for all DVR recordings
I think you’ll have to post process the files to get a .mkv container.
EDIT: Another thread talking about it.
