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. Interlaced sources may need deinterlacing for clean playback. Encode MPEG (MPEG-2 / MP2) from ASF at a bitrate near the source, and confirm the audio track before converting.
