There was a battle of which is better...and the industry just decided to really not expose to much blue-ray marketing due to the fact that many movie companies didnt want to use the blue-ray theory due to the cost. More regular DVD's are sold than blue-ray. But if you have the same movie in both forms...um...get rid of one I guess. Plus they take up lots of space...which is why I rent online...lol...my opinion...blue-ray is no different. Laterz!
