It looks like they increased the playback.
When they showed reruns of The Flintstones and Jetsons on Cartoon Network a few years back, they did the same thing.

I think this is actually true of the foreign airings of the He-Man cartoon in the 80's. Because the DVD releases we are able to purchase these days are apparently from those copies, and are played at a bit higher speed than what was aired here in the states. At least, that's what I've heard.
