Tvheadend

I have a bug in tvheadend regarding pvr. If i schedule a recording, tvheadend is delaying ths recording.

if the program starts at 11.00 tvheadend starts recording it at 11.20 and is recording same amount of time after the program stops. Epg is correct, and the same with the time on the server.

i do use 1 min pre time and 10 min post time in pvr profile.
I also seems from time to time a recording is split in 2 files, when trying to see that program in kodi it skips to the last of the 2 files, starting in the middle of the program.
