Description

This hd530c OpenPLi/enigma based setop box has a triple DVB-C tuner (FBC) with for me a still unknown Tuner brand(Broadcom?).

The Mut@nt hd530c currently runs Tvheadend 79ea2a42c477e315ffa2143252273fe2db0c2165 with 3 frontends detected on a single adapter but using its dvb-c adapters directly within Tvheadend causes Tvheadend to crash as soon as a 2nd channel on a different transponder is tuned on a 2nd/3rd tuner. This happens with enigma enabled in background and with runlevel init 4. There has been some Tvheadend optimizations lately(see issues) to improve multiple frontend behaviour on dual tuners but for this FBC dvb-c tuner it did not improve yet.
The good news is that scanning for channels works even on 2 tuners also EPG update.
