Comment (by Klaas de Waal):

 It could be that your SatIP box has become unhappy. I have that
 incidentally when testing and then I reboot the box with the web
 interface.

 I generally have the "Schedule as Group" enabled and then virtual tuners
 are created when needed. This does not change the load on the SatIP box
 that much, only a few additional PIDs are selected. There is a switchover
 point when more than 32 PIDs are selected; in that case all PIDs are
 received and all PID filtering is done by software somewhere. Note that
 this can already happen with a single channel, e.g. channel 101 "BBC One
 London" wants 36 PIDs.

 When I test this with the Raspberry Pi 3B then it can get overloaded
 especially when it is doing EIT on the second input, which can also need
 the full transport stream.
 On a computer with a real 1Gb/s network interface this should not be a
 limitation.

 In your configuration, with (IIRC) a number of inputs configured all to
 receive the same satellite, I would connect all inputs to the same video
 source, select "Schedule as Group" on all inputs and let the system figure
 it all out.
