Creedo, if you are watching the Dailymotion upload, then the video is slightly sped up. So the voices don't quite sound like they should.
Watch the second upload with the JPlayer thing. It takes longer to start, but it's not screwed up like DailyMotion plus you don't have to worry about advertisements popping up several times while you watch it.
OMG am I the only one that thinks their current voices are sooo worse than ever? I mean, compare Gaara's voice at the kage arc and here. Even Naruto sounds much worse. Did they change voice actors or something?
