I am not sure. I might have misspoken.
Now I see that recording of the show "KMFORGET" was started, but then a few minutes later, a Stop command was issued for it. I have not checked whether the stop command actually stopped it. Shortly after the stop command (a few seconds later), another show was started. Again I will have to check whether the show actually was trying to use the same tuner that KMFORGET was using. One possibility is that the second show had a higher priority. There may have been a tuner that was stuck. So MC could not find a free tuner, and thus stopped KMFORGET.
That said, I also saw in your log there were two recording rules that were associated with the show Quantico: KMFORGET. The events that I described in the above paragraph were associated with recording rule ID 608063037. After the recording was stopped, another recording rule showed up in the log, rule ID 523409393. However, this was marked as "not to record", so recording was not started on it.
