I have surfed the web for some official downloads of Shall We Dance movie, and here is what I found:

1. peer-to-peer (P2P)

If you choose this way to download Shall We Dance, your computer will become a part of a huge network. You share the file while you are downloading it. All the participants of the download process will do the same.

I firmly believe it is not a very good choice for dialup Internet users. I have tried some peer-to-peer movie download sites and they seem slow.

2. direct download

If you try to download Shall We Dance from an http server, nobody will download from you - there is only connection between you and the server. My experience shows that downloading via http is quite fast and safe.

An important thing here is to find out whether the server with the movie file supports download resuming. If it does not, you may have to start over when the downloading process stops for some reason.

3. emule/edonkey

Really a torture. My advice is not to use it.

So, to successfully download Shall We Dance movie, you should search for a good, secure and official ftp/http location. Still, in my opinion, the best choice to get this movie is to buy it as soon as it is released on DVD.
