existing recordings with no problem. I'm assuming the

There was a short segment in the backend log that was out of the

When you say short segment out of the ordinary, do you mean the
"Expire autoexpire.cpp:641 (SendDeleteMessages) Expiring 0 MB for
1730 at 2017-04-23T21:42:48Z => Unknown" line?<br>
<br>
I think that is just expiring a LiveTV entry where there is no
guide data loaded so would be symptom rather than cause. The
unknown is because there is no program title when there is no
guide data.<br>
<br>
Can you just run mythfilldatabase from the command line as your
normal mythbackend user (probably mythtv) and does that fix it?
Actually probably should be mythfilldatabase --dd-grab-all.<br>
<br>
If you run from the command line the terminal output might provide
some more clues about what is happening.<br>
<br>
Otherwise maybe worth logging into your Schedules Direct account
and confirming that all is correct there (I don't use Schedules
Direct so don't know what "correct" might look like.)<br>
<br>
There used to be an issue with old cache files that couldn't be
deleted but I thought that got fixed long long time ago. Could
try:<br>
ls -ld /tmp/mythtv*<br>

<font face="DejaVu Serif">Yeah, I ran mythfulldatabase yesterday and
that appeared to correct the problem. I still have no idea what
happened though. What would cause all guide data to be deleted?<br>
