On Feb 24 they will be releasing a 12 dvd set, an 8 dvd set and 12 individual sets. The 12 individual sets have the episodes listed. When you add them up there are 49 episodes on the 12 individual sets. However the 12 dvd set only states over 20 hours and the eight dvd sets says over 13 hours.If you add up the prices of the individual sets its a little cheaper. Does anyone have any idea what is on these sets and why should I buy the 12 dvd collection instead of the individual episodes?
