I'm now killing my secondary vdr instances while the channels are copied by a cron job every night. It would be more practical for remote vdr-sxfe clients to keep vdr processes running to avoid loosing the streaming connection. Is it possible to signal somehow vdr to reread it's entire channels.conf when it has been changed externally? By SVDRP?
It sounds as if you are looking for the epgsync plugin. You can find it here http://vdr.schmirler.de/.
