Chrome and Flash
The best way to watch things that might require Flash(?) like Hulu is to do it through the Chrome browser (not Chromium)
Download Chrome and then install it (I forget the steps).
You may need to also install some sort of flash plugin. In the past I've tried running:
sudo apt-get install flashplugin-installer and then restarting Chrome.
I've Googled and found blog posts like this one with other things to try.
