Ok that's what I imagined, svdrp works,

But the Problem I have is a bit different. Well the solution with this 
syslog-parsing I posted before works.
But it would be much better to get an information about failure from

svdrpsend.pl HITK Key

directly.
To test, do as follows:

1. Start playing a vdr-recording.
2. Open a tty on remote computer.
3. run:
   i=0;  while true; do svdrpsend.pl MESG $i &  sleep 2 ; i=$((i+1)) ; done
 You should see now the messages on the screen.
4. now open a second tty
5. run:
   svdrpsend.pl HITK Pause

Nothing will happen. The playing will not be stopped. But the answer of 
svdrpsend.pl will look like that:

220 mediaportal SVDRP VideoDiskRecorder 1.2.6; Sun Jul 18 14:06:19 2004
250 Key "Pause" accepted
221 mediaportal closing connection

So how can I realize that the action, I asked vdr for, not happend?
Still the only way I see, is parsing the syslog, the way I described in 
my "SOLUTION".

By the way, as I told before, for me it looks like vdradmin sometimes 
has a connection to vdr when the sleeptimer wants to powerdown the 
system (wants to hit the key Power). But I dont know exactly what 
vdradmin sends to vdr. I thought it would not be the svdrpsend.pl MESG 
text, cause vdradmin never sends MESG to vdr, but things like LSTR LSTT 
LSTE and manipulating these lists.
Thats why the above example with this message loop is only for testing 
the trouble that I thougt we have to deal with. Hopefully this example 
reproduces the real life situation with sleeptimer, that I mentioned 
before. But the good result with my "SOLUTION" lets me believe in that 
thesis.
