Yes, and I highly recommend using the official backup/restore scripts to 
complete the process.  If you use mysqldump directly, you may well 
create a backup that corrupts the schema on restore (there are certain 
command line arguments that must be used and others that can't be used, 
and the official backup script uses the right arguments, and the restore 
script checks to ensure everything will work correctly before restoring 
to make sure the process works properly).

See http://www.mythtv.org/wiki/Database_Backup_and_Restore (mainly the 
first and second section) for info about doing the backup and 
http://www.mythtv.org/wiki/Database_Backup_and_Restore#Replacing_an_existing_database 
for info on doing the restore.
