Thank you for your very kind and fast help, Torsten!

Meanwhile, I've found another workaround:
The problem was that the players expected audio data in my mpg files 
(which there isn't), and also mplayer warned about video packets and the 
buffer. With the following command one can fix these mpeg1video files:

mplayer tweaked.mpg -dumpvideo -dumpfile goodmpg.mpv
