The following review written by one of the Software Informer contributors applies to version 3.5
Xilisoft Download YouTube Video is a simple, neat and handy application that allows downloading videos from the popular YouTube website. It looks exactly like the mediAvatar Free YouTube Download program and has the same advantages and disadvantages as that application. Xilisoft Download YouTube Video comes with a neat built-in browser that lets you search for YouTube videos and watch them before adding them to the download list. The download speed is pretty decent and it allows batch downloading multiple videos at once.
The interface is also a positive aspect of this application, as it is very simple and neat. Anyone can use it without any problem, even if they are complete beginners. On the other hand, Xilisoft Download YouTube Video doesn’t feature any conversion possibilities and allows saving the downloaded videos only to the MP4 format, without letting you customize any advanced output parameters such as the bit rate or the frame rate. Anyway, it’s a handy tool worth giving it a try.
