"Beezbo." LCA/New World. $19.95. At a time when courtesy seems to be on the endangered list, this live-action attempt to teach kids the basics of etiquette is a worthy idea. Space alien Beezbo is taken in hand by three youngsters to learn some human manners: handling introductions, setting a table, sharing and tidiness, saying please and thank you. Despite a peppering of intended humor and special effects, low-budget production values and awkward acting are reminiscent of many '50s and '60s grade-school educational films, making "Beezbo" a long 48-minute sit.
