[BUG] Playback Error after some time playing Live TV

If I plays Live-TV after a while the Program stops. Somtimes after some Minutes and sometimes I can watch TV a Day or longer and change the channels. There is the following message:
“Playback Error
Unable to tune channel”. After this message I can’t play any channel or record it. The Tuner is shown correctly in Live TV & DVR:
EyeTV Netstream 4Sat
4 Tuner
1317 channels—
63 active channels

I just have to restart my Synology NAS DS918+ and all works fine. Could you fix this Bug?

Attached the lox after this error before restarting.
