Does anyone know where I can find video from the show to create fanvideos?

I am trying or at least wishing to start making fanvideos for Heroes. I have Final Cut Express and uTorrent but I can't find any useful and seguro vídeos of the show to use. I've searched with uTorrent Isohunt and found websites but none of them are seguro to use or they have poor quality. If anyone knows, please help and let me know! :D
