 After the reports on list, irc, and the SD forums indicated that there was
 an issue with the MythTV HDHomeRun recorder repeatedly issuing set filter,
 I have performed a git bisect of MythTV, and the result is that the first
 commit that is causing the problem appears to be
 9b22460f53bf6313516f33987e4260897c6076a3 which is "Merge of various
 recorder changes from mythtv-rec2".  This seems to generate new filter
 updates hundreds (or more) times per second.  The second commit
 0542a100237dd26bcbc60212c443f4619586f15b "Refs #10414. Lower HDHomeRun
 recorder CPU usage a tiny bit more." sets a timer to only update the
 filters about 10 times per second (the currently observed rate).  For
 testing purposes, I have created a patch against fixes/0.26 which updates
 the filter on the hdhomerun only when the code indicates that the filter
 list has been changed (attached).  It should not be considered complete,
 but simply as a proof of concept.  In particular, I have not looked at EIT
 filter changes, nor other recorders.

 Kenni Lund suggested that I submit this ticket.
