It seems to be a software/hardware issue. It seems that the FF card displays only a single field of the frame twice (to avoid flickering one pixel horizontal lines on TV) short time after not further data arrives (typical for still frames). And displaying just a single field removes halve of the information to display. Bye. -- Dipl.-Inform.
