Most of the edits on Naruto are minor. The one really stands out that I can think of is Loopy Fist Lee who drinks Eilxer. I remember in the old day that Gundam Seed having colors painted on guns to make them lasers or Flay telling Sai that she was in Kira's room doing the naughty got replaced with her and Kira are dating.
As long we got subs and dvds, it ain't a big deal. Besides, why on Code Geass do I want to see some Pizza Hut sign or want to sued CN for not showing me Kallen's boobs, If I do that, I'm nothing more a pervert.
