Comment (by kmpatel@…):

 Yeah, I don't have this problem with a HDHomeRun tuner, just the V4L.

 As requested.  I've attached a file showing the output of "mythbackend -v
 network"

 Also, illustration of the problem on a backend with a V4L tuner.  I have 4
 event test handlers, shown below:

 {{{

 +---------------------------+-----------------------------------------------------------------------------------------+
 | value                     | data
 |
 +---------------------------+-----------------------------------------------------------------------------------------+
 | EventCmdRecFinished       | echo `date +"%F %T"` "<-- recording
 finished: %FILE% %TITLE%" >> /tmp/backend.event.log |
 | EventCmdRecPending        | echo `date +"%F %T"` "<-- recording pending:
 %FILE% %TITLE%" >> /tmp/backend.event.log  |
 | EventCmdRecStarted        | echo `date +"%F %T"` "<-- recording
 starting: %FILE% %TITLE%" >> /tmp/backend.event.log |
 | EventCmdRecStartedWriting | echo `date +"%F %T"` "<-- writing file:
 %FILE% %TITLE%" >> /tmp/backend.event.log       |
 +---------------------------+-----------------------------------------------------------------------------------------+
 }}}

 As you can see below, however, that during the recording period (between
 7:28 and 8:02) there is no output for "EventCmdRecStartedWriting".  But
 the event handler is configured properly, as witnessed by the manual use
 of mythutil --systemevent REC_STARTED_WRITING a few minutes later @
 08:14:55.
