Starting point: MKV - Multi-track container for video, audio, subtitles. Only the selected tracks carry over, so pick audio and subtitles first. Quarter-pixel motion can strain old decoders; convert for playback. Encode Xvid (MPEG-4 / MP3) from MKV at a bitrate near the source, and confirm the audio track before converting.
