I believe I have found where the messages are coming from, however I have yet to figure out the cause.
Today kodi.log contains these 3 entries:
06:00:37.694 T:3847222112 WARNING: CreateLoader - unsupported protocol(pvr) in pvr://channels/tv/All channels/pvr.hts_1873343440.pvr
06:00:37.694 T:3847222112 WARNING: CreateLoader - unsupported protocol(pvr) in pvr://channels/tv/All channels/pvr.hts_365774006.pvr

And, if I look at the files table in the database MyVideos107.db, I find this:

I know that if I rebuild the Videos DB the entries in the log go away for a while. I also know the entries in the log happen each time a videodatabase cleanup is done.
So, what's the cause?
TIA
