The sex scenes in the Double D Productions DVD were edited to about half the length of the Big Top VIdeo DVD, accounting for the difference in run times. Otherwise the versions are identical.
After a popular Dukes 1, this is a quick cash in on it's success. Same format to a tee, except a another actor is playing the Duke. Some different big busty girls, but overall a fairly basic movie. The highlight is a topless game of tennis.
