Vuze 4: Combining legal, less legal BitTorrent networks
The problem is that the people who were already familiar with Azureus, which was renamed Zudeo and then Vuze, were used to getting their media for free, so it's a bit tricky trying to convince them to pay. A few months back, Vuze tried to make its platform a bit more attractive by adding social features. But more importantly, Vuze 3.1 made it easier to search for videos hosted on sites besides Vuze. So you could find legal videos, but you could also search sites like Btjunkie and Mininova for slightly less legal files.
Vuze 4 was released this week, and like in Vuze 3.1, the Torrent search box is front and center, making it almost easier to find illegally shared videos than the legit cntent from the "Vuze HD Network" that Vuze really wants you to find. The goal is undoubtedly to attract back some of the BitTorrent users who have fond memories of Azureus but have since migrated to other platforms with a slick client that lets you search for, download, manage, and even watch videos from a variety of sites.
The paid downloads seem to be gone, but select content in the Vuze HD Network (not all of which is available in high definition, by the way), is ad-supported. For example, you can watch Season 1 of Dexter for free if you're willing to put up with a few ads. And if you don't bother trying to download the ad-free DVD rips from another site first.
