5KPlayer is a complete application that can be used to play music, watch video/movies and also download video from online video service. It supports various websites including YouTube, Vimeo, and many more. The list of supported websites is listed here.
I haven’t tried 5KPlayer to download video from other websites. I was trying to download video from YouTube and expecting that it can download restricted videos from YouTube. But unfortunately, this 5KPlayer is not more than any other free YouTube video grabber, which only works for unrestricted videos.
Hmm…5KPlayer, has many features but I think its not for me….keep looking for other software.
