The bandwidth-intensive Joost client presents you with a full screen interface.
The new beta features a redesigned UI that is more "Mac-like" with beautiful, translucent controls and widgets that exploit OS X.
Joost presents you with a full screen interface and a deep channel guide organized into categories.
From there it's pretty simple, click on a channel and watch.
Channels can take some time to load.
They've also added some new channels, including a games channel, a manga channel, a football channel, a Guinness World Records TV channel and more.
Joost offers a number of social features like My Channels and Sharing.
Previews some times don't ever load - but that could be a bandwidth issue.
