Thank you kindly, Hyc!
If I may offer some additional instructions:
Code:
get_flash_videos --add-plugin http://gitorious.org/get-flash-videos-plugins/gfv-plugins/blobs/raw/release/Hulu.pm
You will also require libcrypt-rijndael-perl, which is easily obtained.
Enjoy it while it lasts, Hulu is likely reading this right now. Watch the commercial anyway and don't share the videos. I, for instance, only download so I can watch it without stutters.
