Starting point: MKV - Multi-track container for video, audio, subtitles. Only the selected tracks carry over, so pick audio and subtitles first. Protected store files cannot be converted; use DRM-free sources. Encode WMV (WMV2 / WMA) from MKV at a bitrate near the source, and confirm the audio track before converting.
