mythconverg_backup.pl --rotate 20 --verbose 2>&1 | tee $HOME/backup.log

Then, after capturing the above to find out what's happening, now, make 
sure someone else isn't running the script with conflicting arguments.  
The best way to do so is to ensure you (and all users of the script with 
the same DB backup directory) use a backuprc file with the appropriate 
configuration.

echo "rotate=20" >> $HOME/.mythtv/backuprc

Then, don't specify --rotate on the command line.

Also, when MythTV calls the backup script to create the automatic 
backups (when a schema version upgrade takes place), it uses the default 
5-backup rotate value.  I'll change that so it disables rotate for 
automatic backups (later today).  Perhaps the last automatic backup just 
deleted all but 5 and you've only done 4 backups since (your DB schema 
was last upgraded)?
