[mythtv-users] Recording Functionality Breaks Regularly Since Upgrading to 0.25

Greetings (and apologies for original message which included html, I
hope this is better),
Ever since upgrading to 0.25 from 0.24 my system spontaneously fails to
make recordings.
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. Aside from the regular
breaks in recording capability, the system performs more or less
identically to when it was running 0.24.
Whether the recording functions are working or not, there is no issue
with playback of successful recordings (suggesting this is not a
harddrive I/O issue).
I followed Mike's advice to another user with a similar issue
(http://www.mythtv.org/pipermail/mythtv-users/2012-May/333505.html):"'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.
Portions of my backend.log during a failure are attached.
Suggestions welcome.
Brian
