The following review written by one of the Software Informer contributors applies to version 2.2
ALL YouTube Downloader is a very simple and light application that allows you to download videos from YouTube. It does not offer any help, but you will hardly need it thanks to the program's intuitive interface. In addition, it allows you to add several YouTube videos for downloading to create a download list, and then tell the program to grab them all at once.
The program installs a plug-in for Internet Explorer that allows you to download any video you are currently watching directly from your browser. However, if you use Mozilla Firefox or SeaMonkey, you will need to download and install an add-on separately to do the same. If you use any other Internet browser, you will not be able to enjoy this handy feature.
The program allows you to add a video to the download list manually by pasting its URL. Every time you add a new video, the program will prompt you to select the download location and the output format (which you pick from the list of source formats). Finally, you can select all the elements on the list - or just some of them - and tell ALL YouTube Downloader to grab them. The download process can be stopped at any moment, so don't worry about feeding too many videos for grabbing.
