It is a super hack job and could really be cleaned up, but here is my
script, I found I have to hard boot the hdpvrs twice to get it to
work, which is what the iboot.pl script does:

logerror=`grep 'Recorder Failed' /var/log/mythbackend.log | tail -1`
if [ "$logerror" ]
   md5=`echo $logerror | md5sum `
   md5=`expr "$md5" : '\([0-9a-z]\+\)'`
   previous=`cat /var/tmp/pvr-fail-previous | grep $md5`

   echo "HDPVR Recorder Failed: $logerror ">$EMAILCONTENT
   if [ "$md5" != "$previous" ]
        /bin/mail -s "$SUBJECT" "$EMAILADDRESS" < $EMAILCONTENT
        rmmod hdpvr lirc_zilog lirc_dev
        sleep 25
        modprobe hdpvr lirc_zilog
        sleep 25
        /etc/init.d/mythbackend restart

   echo $md5 > /var/tmp/pvr-fail-previous
