When you launch zButterfly, you will see a series of films ready to be downloaded on the main page. But this BitTorrent client will allow you to search for any film that you want to see. zButterfly will offer you a list with the downloads available, and you will only have to choose one and start the download. You will be able to see the download process, and it also offers you the possibility to see various statistics.
zButterfly also allows you to link several devices with the application, like an iPod, iPad or iPhone, to be able to play the videos that you have downloaded on any of those devices. You only have to drag and drop the video on any of the terminals that you have on the list, and you'll be able to play them from there. It's also capable of detecting applications installed on the computer with which it's possible to view videos.
