put some commands into the vdrshutdown skript (something like
    who | wc -l
and decide depending on the output, if you would like to shutdown your
machine or not.

I never did that myself, but something similar should work.

just call
   svdrpsend.pl "HITK Power"
(or something similar, I don't remember the syntax right now)
instead of
   shutdown -h now

this will
  - do nothing if a timer is active or if there is one in near future
  - set the appropriate times into BIOS and shutdown otherwise.
