Hey dios you can get all the info you need at http://www.teambg.net/forum/?board=94. I would use Emule although there are other options. Let me know if you like it.
As I use a small variety of downloading files, this thread on downloading TDD led my mind to a sidetrack (as usual): is it possible to d/l the really big files like TDD, BGT, etc. as torrents and, if so where ?
