Pavtube YouTube Converter is a video downloader and converter. It can be used to download any video from YouTube.com. You can also convert the videos that you want. This is optional, which means that you can either download FLV files or have them converted to other formats after they download automatically. There are lots of formats supported. All the popular ones are there, including H.264 and MPEG-4, which you will need if you want to play the videos that you download with this tool on your Apple devices.
The graphical user interface of this app is very basic. There are four buttons on the top, which let you start a new download, change the settings, access the help section and buy the full version of the app. From the bottom of the screen, you can change the state of each download, with buttons like stop, delete, and play.
Unfortunately, at the time of writing this review, the application wasn't working. Every single video URL that I tried returned a "failed" error. I tried several different types of videos, too, but to no avail.
