Until now for me the best downloader – at least considering the extremly wide range of compatibility to web sites!
1.) VVCAP offers (almost) all that, what modern webbrowsers offer. including the ability to sing in to sites.
2.) The results for downloads include to choose between different offered resolutions or, if you like to, just the audio track.
3) Aafter just a few minutes you will have understood how this program is to handle.
All in all it is an easy to use and effective tool for the anounced purpose!
