I have reoccurring problems with a specific service when this has been accessed from a SATIP client.
From tvheadend's log, I've narrowed it down to this event:
satips: 0/CD729681/3: create mux DVB-S2 freq 11523200 H sym 22000000 fec 2/3 mod PSK/8 roff 35 is_id -1 pls_mode GOLD pls_code 0
tvheadend is recent: 4.3-2323
SATIP client is a Gigablue box, running vtuner as the integrated SATIP client/tuner. The only information I have is this package information: satipclient - 1.0+git96+d362630-r0 - satip client using vtuner (source probably hosted here: oe-alliance/satip-client)
I will give it a try from a Panasonic TV with an integrated SATIP tuner, to see whether it will cause the same problem.
So far, I was only able to observe this behavior with the mentioned service/mux.
