hiya, I'm having the same problem, I've posted up questions and emailed people all over the place, but nobody will help :( i have dvd decryption software, and shrinking software too, but I can't make them small enough so that people would want to download them :(
once i had managed to shrink something feasibly small enough, i created the torrent (you need to put it into your download folder so that people can upload from you) and did all the right stuff, i searched for it, but could not find it
you could try google and search for 'how to create a torrent in (software that you use to download)'
anyway, if you have any luck on the decryption and shrinking thing, i could help you with the next bit
good luck hon
