Limits
Starting point: MPEG - MPEG is the ISO program-stream container behind MPEG-1 and MPEG-2 discs. Interlaced sources may need deinterlacing for clean playback. Protected store files cannot be converted; use DRM-free sources. Encode WMV (WMV2 / WMA) from MPEG at a bitrate near the source, and confirm the audio track before converting.
