<p style="margin-bottom: 0in;">Greetings,<br>
</p>
<p style="margin-bottom: 0in;">Ever since upgrading to 0.25 from
0.24 my system spontaneously fails to make recordings.<br>
</p>
<p style="margin-bottom: 0in;">Generally 12 hours or so after the
last reboot, after having made scheduled recordings normally in
the interim, the system will attempt to make scheduled TV
recording(s) but fail. After a reboot, the system will resume
recording scheduled programs but once the backend breaks, it will
remain broken until the host is reboot (stopping/restarting the
backend makes no difference). The recordings menu (Watch
Recording-->All Programs) will display normal menu entries for
all recordings which were attempted (successful or not), but no
HDD recording will have been made once the backend breaks and of
course, no thumbnail image will be evident in the menu. If you
attempt to play the none existent recording, a pop-up reads
"Recording Unavailable <showname> The file for this
recording is empty." <br>
</p>
<p style="margin-bottom: 0in;">Aside from the regular breaks in
recording capability, the system performs more or less identically
to when it was running 0.24 and whether the recording functions
are currently working or not, there is no issue with playback of
prior successful recordings (suggesting this is not a harddrive
I/O issue).<br>
</p>
<p style="margin-bottom: 0in;">I followed Mike's advice to another
user with a similar issue (<a class="moz-txt-link-freetext"
href="http://www.mythtv.org/pipermail/mythtv-users/2012-May/333505.html">http://www.mythtv.org/pipermail/mythtv-users/2012-May/333505.html</a>):"'Delete
all capture cards' (not 'Delete all capture cards on
<hostname>'), then re-create cards and re-connect inputs"
but this made no difference. I've also physically reseated my
digitizer card after cleaning the contacts.<br>
</p>
<p style="margin-bottom: 0in;">Portions of my backend.log during a
failure are attached.<br>
</p>
<p style="margin-bottom: 0in;">Suggestions welcome.<br>
