As for logging, add some:

echo $?

(to get return status of commands) as well as some redirects:

LOG_FILE=`mktemp -t mythlink_XXXXXXX.log`

/usr/share/doc/mythtv-backend/contrib/user_jobs/mythlink.pl --link 
/home/mark/MythRecs --chanid %CHANID% --starttime %STARTTIME% --format 
'\%T/\%T-\%Y\%m\%d-\%H\%i-\%S-\%cN' 2>&1 | tee -a ${LOGFILE}

to the script (where the above would write data to some file, like 
/tmp/mythlink_yYiE5gU.log ).
