Potentially a great program if someone spent more time on it. It did successfully download two music videos from Youtube in the desired format and to the specified location which many video downloaders struggle to achieve. However the GUI needs a lot more work done to it. The 'save cofig' box is always greyed out and it is not possible to paste the video URL into the program because it does not permit right click commands. Therefore it is necessary to use Ctrl + V to paste the URL into the program. The program does not detect and list the formats and resolutions avalable for the video and provide the user with the options of choosing these formats and resolutions from a list with radio buttons. Therefore If you choose 'HD' from the GUI you may obtain 1080p or 720p resolutions. I suppose we ought to be thankful that the program is updated 5 - 8 times a year so that it can keep up with changes made by Adobe and Youtube. Incidentally I am using Java 7 update 25 and Windows XP SP3.
