Tvheadend

I am using TVHeadend Version 4.1 connected to Kodi Version 16.1, all running under Linux.

When watching timeshifted Live DVB-T TV (in Australia), sometimes when skipping forward, the TV Channel being watched will change, and the timeshifted recording will be lost (or at least I can't get back to it). I have the Timeshift Buffer to 100,000 and the Maximum Timeshift Period to 120 minutes.

This issue most consistently occurs if the Live TV has been paused for a period of time that means that the current program has ended and another program has started. When skipping forward, when you get to the end of the first program, instead of proceeding to skip into the second timeshifted program, the system changes TV Channel, and the timeshifted programms are lost.

Can anyone advise what might be wrong in my TVHeadend configuration to cause this problem ?

Thanks.
