 The mythtv backup scripts exists with error code 2 and does no backup if
 root has an .my.cnf file for mysqldump with different user.

 The reason is already described in then code of "mythconverg_backup.pl":

 {{{
         verbose($verbose_level_debug,
                 '', "Attempting to use supplied password for $mysqldump.",
                 'Any [client] or [mysqldump] password specified in the
 MySQL'.
                 ' options file will',
                 'take precedence.');

 }}}


 By reading the /etc/default/mythtv-backend file and using sudo if the
 mythv user is set,this could be solved:

 {{{
 #!/bin/sh
 # /etc/cron.weekly/mythtv-database script - check and backup mythconverg
 tables

 set -e -u

 DBNAME="mythconverg"
 DEBIAN="--defaults-extra-file=/etc/mysql/debian.cnf"

 /usr/bin/mysqlcheck $DEBIAN -s $DBNAME

 if [ -e "/etc/default/mythtv-backend" ]; then
    . /etc/default/mythtv-backend
 fi

 if [ "$USER" = "" ]; then
    CMDPREFIX=""
 else
    CMDPREFIX="sudo -u $USER"
 fi

 $CMDPREFIX /usr/share/mythtv/mythconverg_backup.pl

 /usr/bin/logger -p daemon.info -i -t${0##*/} "$DBNAME checked and backed
 up."

 # End of file.

 }}}

 the changed code is:

 {{{
 if [ -e "/etc/default/mythtv-backend" ]; then
    . /etc/default/mythtv-backend
 fi

 if [ "$USER" = "" ]; then
    CMDPREFIX=""
 else
    CMDPREFIX="sudo -u $USER"
 fi

 $CMDPREFIX /usr/share/mythtv/mythconverg_backup.pl
 }}}
