Description (partial)

DVB subtitle burn in does not support SD subtitle to be inserted on a HD stream.  The subtitles are incorrectly positioned in the stream.

The display definition segment (DDS) (if present) in the subtitle stream defines the target resolution for the coded subtitle payload. The absence of a DDS implies that it may be assumed that the subtitle stream is coded with a display resolution of 720x576. If the video content is different from 720x576, the subtitles will be incorrectly positioned.
