One more thing: the 'file' command reports MPEG sequence, v2, MP@ML interlaced Y'CbCr 4:2:0 video, 4CIF PAL, 4:3, 25 fps on a file created with the posted script (before the mplex call), while for your noSignal.mpg it reports MPEG sequence, v2, MP@ML interlaced Y'CbCr 4:2:0 video, CCIR/ITU PAL 625, 4:3, 25 fps Maybe this indicates where the problem might be?
