Hi Peter,
yes, the "killing thing" was my first idea also. But since it is
not that gentleman like, I asked here for another solution.
In the meanwhile I found this:
tzap -r -H -t <duration in seconds> -o - <channelname from
~/.tzap/channels.conf > "filename"
records the stream into "filename". The redirection is necassary,
since tzap gets problems when trying to write more than 2Gigs of
streamed data.
I start this via fcron.
