This line shows me, that a TS packet (188 byte: 4 byte header + 184 byte 
payload) was lost. When the recording ended, you should get a couple of 
TS discontinuities reported in syslog.

The remuxer cannot recreate those lost bytes, but just inform about this 
issue. Next, one has to check, why TS packets get lost: driver isssue, 
hardware issue, etc.?

The signal may be strong enough, but it could also be a matter of the 
driver or hardware setup/configuration that packets get lost.

Possibly, because it is a different hardware/setup/configuration.

Do they all have similar hardware/setup/configuration?
Are there other people without this issue?
