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. Captures may start mid-packet; trim the lead-in after conversion. Encode TS (H.264 / AAC) from ASF at a bitrate near the source, and confirm the audio track before converting.
