First off, the key to using the ed2K network is patience. It's not a network for grabbing one file at a time, you need to queue up a lot and your client (which should be an emule mod, not eDonkey BTW) can grab lots of chunks of lots of movies.
My internet connection is only on from 6.30pm to 11:00pm at most, and I do quite well out of it. Not as well as some, I'm sure, but I'm happy.
Also, at the beginning your downloads will be slower until your client builds upload credit. Once you've been sharing for a while you should be able to get close to maxxing out your connection with a healthy queue.
