Tvheadend

Hi guys,

I'm trying to record with my tvh on my Raspberry Pi 4 with Raspbian Linux 10 (BUSTER) and I always get the same error - "Time Missed".
My Log File says:

2020-12-12 09:59:54.133 [WARNING]:mpegts: too much queued input data (over 50MB), discarding new
(very often...)

10:10:24 was the first start for the record... With the error "Time Missed" the TVH Service freezes...

Anyone an idea?

THANKS, Andy
