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. Closed-caption tracks need separate extraction before conversion. Encode LXF (MPEG-2 / PCM) from ASF at a bitrate near the source, and confirm the audio track before converting.
