Tvheadend

Hi everyone,
I have implemented the htsp method updateDvrEntry in TVHClient. I only provide the fields that the webinterface provides when changing a recording. These are 'title', 'start', 'stop', 'startExtra', 'stopExtra'. When I execute the method on a scheduled recording it returns success and the server also sends the htsp message 'dvrEntryUpdate' but with the old date. The changes are not saved. Additionally the scheduled recording is immediately removed. I checked it in the webinterface.

I see these messages in the log when I update the scheduled recording 'Madagascar'.

May 24 12:26:40 localhost tvheadend[1393]: htsp: 192.168.178.20 [ xbmc | org.tvheadend.tvhclient ] - method updateDvrEntry
May 24 12:26:40 localhost tvheadend[1393]: settings: saving to /home/hts/.hts/tvheadend/dvr/log/bbf7ca8a9dd4e4d3b8797114d1f1f9b3
May 24 12:26:40 localhost tvheadend[1393]: dvr: "Madagascar" on "SAT.1": Updated Timer

Additionally when I change a recording from the webinterface the htsp message 'dvrEntryUpdate' is not send to the client. So the client does not get updated.

Can someone help me with these two problems?
