[mythtv-users] Debugging hdhomerun - can I record the same show from multiple tuners in duplicate?

[Ram Ramesh]

Hi,

  I have two HDHomeRun tuner boxes (a dual and another quattro) and I 
suspect one of them is broken. I strongly feel it is the quatrro, but 
for now, I am going to assume that anyone of them could be broken 
because the only evidence I have is that some shows turn out to be 0B 
recordings. I have already power cycled and tested with hdhomerun 
control/config app on win10. They seem to work fine when watching live 
TV in myth also. However one of the boxes very often produces 0 bytes 
recording.  I would like to record the same show on of both my tuner 
boxes at the same time to check if this is a transmission issue or tuner 
issue. My antenna is brand new and I doubt it is at fault.

   Both units are several years old, so it could be that their adapter 
is broken. If so, my app on windows should create problem or attempting 
to watch live TV should produce errors, but I do not get any of those. 
So, I have not tried fixing adapters

   Also, when I added my second HDhomerun unit (quattro) when I bought 
it, strangely enough, I got 8 tuners instead of 4. So, I am not sure if 
something is wrong with backend setup of this tuner.

   I run standard debian 11.6 with default kernel adding mythtv 
0.32-fixes using debian-multimedia repository. I have a gt1030 nvdia 
card, but that is unlikely to be relevant as this is a recording issue.

   Recording that produces 0B is coming on digital channel 18 
(Dallas/KTXA-DT 21.1)

Regards
Ramesh
