Haha, you totally need to! I bought two of the remastered TV DVDs last week, where it isn't just remastering but they actually reanimated lots of parts of the final episodes from scratch (and added in new shots they couldn't afford before), where they had run out of money and the animation was terrible. I hadn't seen them before since the American release was the crappy aired version, and was geeking out SO HARD.

They put both the crappy original air version and the updated version on the DVDs and I was like *_____* IT'S SO PRETTY! AND ALSO THIS IS HOW YOU MAKE A SPECIAL EDITION UPDATED DVD GEORGE LUCAS OMG HOW AWESOME THAT I CAN WATCH THE FUGLY VERSION AND THEN THE PRETTY ONE BACK TO BACK AND MARVEL AT THE DIFFERENCE. So, um, remastered versions = highly recommended when you watch!
