Starting point: MKV - Multi-track container for video, audio, subtitles. Only the selected tracks carry over, so pick audio and subtitles first. Copy-protected purchases cannot be converted; use DRM-free sources. Encode M4V (H.264 / AAC) from MKV at a bitrate near the source, and confirm the audio track before converting.
