Comment (by Jim Stichnoth <stichnot@…>):

 Hard to believe this is a dupe of #9144.

 I attached gdb to the deadlocked mythfrontend process and got a backtrace
 (attached).  I have several patches on my system, so don't necessarily
 trust the line numbers.  The edit thread is waiting on the decoder thread.
 It appears that the decoder thread is calling
 AvFormatDecoder::ProcessDVBDataPacket() which is calling
 TeletextDecoder::Decode() (which seems strange for a U.S. OTA recording)
 which is blocked trying to lock the OSD.  This deadlocks because the
 editor thread acquired the OSD lock in TV::ProcessKeypress().
