Limits
Starting point: ASF - ASF is Microsoft's streaming container that usually wraps WMV and WMA. Live-archive headers can confuse players; remuxing usually repairs them. No audio can be stored, so pair it with a separate track. Encode MPV (MPEG-2 / AAC) from ASF at a bitrate near the source, and confirm the audio track before converting.
