1 year ago @bennettpeter What makes a video recording have "mkv subtitles"? Are you referring to the file type, video format or codec? Could you please post a clip illustrating the issue?
The reason I ask is that video files with mkv subtitles seem to play fine in the video player on my v33 system, e.g. this mkv clip I made from an Xfinity Monterey ts type recording using Avidemuxer's MKV Muxer output format. mtb.mkv.zip
