get_flash_videos wont work with some HULU videos

[niubhacker]

I am using get_flash_videos 1.24 (the latest version with perl 5.8.8) and its Hulu plugin. But it failed to download some Hulu videos.
For example:

get_flash_videos http://www.hulu.com/watch/221132/abc-world-news-with-diane-sawyer-made-in-america-the-quest-for-american-jobs

Output:
