Most of the ones that I have downloaded hasn't been as good as I know the DVD would be. Also, do you get a lot of fansubs? Generally, the official subtitles are better too. I don't know if you've been getting weird subing. (I think at one point a friend of mine downloaded an anime with a character whose name was "Dr. Jackal", and they translated this as "Dr. Woofe". and another character's name was "Juubei", and they translated it as "Serbavy". I vaguely remember them adding random words in too... >.>;; I'm willing to bet you aren't getting stuff this crappy though.)
