right, that was it.
the only deficiency is that i can't send it into background ( --daemon ),
see threat <start by system-v script>, so the script never reaches the
end:
root 406 259 0 17:59 ? 00:00:00 /bin/sh
/etc/rc2.d/S99vdr-1.1.x
maybe usage of debian's start-stop-daemon is completely obsolete now...
to summarize, here's the ( working ) system-v script:
root@streamer:~# cat /etc/init.d/vdr-1.1.x
#!/bin/sh
#
# startup script for the 'video disc recorder' and its drivers
