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
#
# description: video disc recorder dumps your dvb streams on disc
