Introduction:

The YTD Video Downloader version 4.0 allows you to download unlimited HD and HQ videos from a number of sites such as YouTube, Vimeo, and Blip.TV, and also gives the provision to change their format. It is very easy to use; you just need to copy the URL of the website from which you want to download the video and press the download button. The graphic user interface has tabs through which you can carry out various operations like playing, downloading and converting. A new activity tab has also been introduced in this version which allows you to keep a track of the files which are being downloaded.

Pros:
