I personally haven't used it in quite some time. It worked fine for me, overall. I just did not like the fact it didn't use my default resolutions (set on Hulu.com) which I always set to the highest available. I use the Hulu desktop app.
No video? Are you getting video for other online video apps? What about Hulu.com or the Hulu desktop app? From the brief information, I'm thinking it's the machine or a video driver issue.
