Awesome! Especially if you are behind firewall at work and cant access video sites
Adobe® Media Player software provides control and flexibility to view what you want, when you want — whether online or offline. You can queue up and download your favorite Internet TV content, track and download new episodes automatically, and manage your personal video library for viewing at your convenience.
I’ve tried this out and, I’ve been very impressed so far. Silverlight also seems promising but, I have only used it with Netflix.
