[Reset ticket defaults and fixed formatting]

Almost definitely one or more null characters in data for one or more channels or in program data for one or more recordings. See http://www.gossamer-threads.com/lists/mythtv/users/562355#562355 and http://www.gossamer-threads.com/lists/mythtv/users/562373#562373 and http://www.gossamer-threads.com/lists/mythtv/users/562405#562405 .

While this is uncommon, to prevent issues due to bad (or just plain nasty) data from broadcasters and listings suppliers, we'd need to scrub any channel data discovered in channel scans or "Fetch channels from listings provider" downloads, as well as data from EIT and data downloaded from listings providers and remove--at minimum--any null bytes.

Please inspect your data in your database and see if you can identify any null bytes. Also, please attach full log files showing the errors you get when entering Watch Recordings. See https://www.mythtv.org/wiki/Posting_Logs

    initial v1  
    11New installs die after a few days ruuning fixes/0.27 (v0.27 (v0.27.5-71-ga62fc0d) with all updates per ticket #12611. System built on January 18th works correctly until January 21st.  Symptom is- after scheduling and recording over days suddenly Media Library-Watch Recordings  shows no recordings available.  Backend log shows backend is continuing to record previously scheduled programs.  Only backend error message around that time is:
