Help needed - rtmpdump with hulu plus on Windows

[GunvaldLarsson]

Hey guys. I'm new to rtmpdump and I've been trying all day to download a video from hulu plus.
I've tried using rtmpdumphelper with firefox (when using Chrome, nothing happened), most often, hulu responds with "D'oh! This video wont load. Try reloading this page or checking your Internet connection to see if that helps." and rtmpsrv gives me this:

Closing connection... done!

I don't understand how to sniff urls from hulu. Tried Orbit ++, URLSnooper 2 and Wireshark, but I don't know what to do. But even if I had the url, how would I provide rtmpdump with my hulu plus username and password?

I need very informative step-by-step descriptions. Please.
