Starting point: MKV - Multi-track container for video, audio, subtitles. Only the selected tracks carry over, so pick audio and subtitles first. Closed-caption tracks need separate extraction before conversion. Encode LXF (MPEG-2 / PCM) from MKV at a bitrate near the source, and confirm the audio track before converting.
