Maybe it's a feature to stop flickering one pixel high horizontal lines in still images by doubling one field of the frame. Maybe there exists a switch to turn this feature off. You've tried to repeat an I frame forever. Try to remove the sequence end code (00 00 01 B7) from the end of the file before mplexing and the MPEG program end code (00 00 01 B9) from the file after mplexing. Maybe remove everything up to the first video PES packet from the final file. Bye. -- Dipl.-Inform.
