Hi,

The problem is, that as long as the command from reccmds is running vdr is
"blocked" (it accepts the SVDRP connection but cannot process it) so the
command get lost and the connection is terminated before vdr can process it.

I made myself a small script for such cases:
send.sh:
------------------------
#!/bin/sh
sleep 1
svdrpsend.pl $@
------------------------

Which i call from my vdr scripts like:
-----------------
# do something
# do another thing
send.sh GRAB /blah.jpg &   # the & is the important thing
-----------------
So the main script ends because the other script was called with & and vdr
is ready to accept the message.

Ciao Ulrich
