Hi

Thanks for your help. I have a fairly complicated 'SetWakeupTime' and
'CheckState' scripts as described in my earlier post..

http://lists.mythtv.org/pipermail/mythtv-users/2014-April/362416.html

which I have been using for over 7 months. I have the right permissions
in the sudoers file. Also, since April, I have made changes to the
script so that the wakeup times are persistent between reboots by moving
some of the files out of /tmp. These scripts have been working well for
me and this is the only time they have failed in the last 50 or so
recording attempts.

Since posting this, I have looked around /var/log and every indication
is that the system never 'woke up' at the time. If this is a bug in my
script that has caused this, I sure would like to know and fix it.

Thanks
