I know the error you're referring to...you get that if MythContext
(used by optimize_mythdb.pl as of 0.21) can't find valid login info,
-or- if your home directory is set to /, as is often the case when
running a cron.

In my cron scripts that run those processes I just set the HOME to /home/mythtv:

export HOME=/home/mythtv

For optimize_mythdb.pl you'll also have to make sure that home has the
file ~/.mythtv/config.xml with the correct login info, as that's what
the perl module is using.
