    Yes, output from cron processes is sent via e-mail to the owner of the
    process using local mail delivery agent. This is the standard way it
    works. SURPRISE! (he he, just kidding, but this has been hapenning for
    at least 15 years.)

    If you were running the process in the root crontab, then the output of
    the commands will be sent to the root user via local "mail" command.

    If you want to stop this, you can redirect the output of the mplayer to
    a file every day.... for example, in your crontab have something like
    this: (Remember to remove the newlines, this is wrapped at 80 chars)

    3 4 * * * rm -f /var/log/mplayer.log; mv /var/log/mplayer.log
    /var/log/mplayer.log.yesterday; mplayer -command -options blah blah >
    /var/log/mplayer.log 2>&1

    This command will create a new log every day, and keep yesterdays log
    too, but will lose all older logs.
