OK, I'll explain the link-bit. On certain websites (like shareconnector) you can find links to files available on Emule and/or Overnet. This is something you can do instead of using the "search" function and I prefer to get files this way, as the probability of getting the correct movie is higher (there are plenty of fake files).
With Overnet you don't have to worry about choosing server, and my experience is that files will start downloading faster on overnet than on emule.
For finding links (to files) check out the forum at shareconnector.com.
