The manufacturer, from which I bought my mac dvd& video converter, sent me a newsletter and recommend the Mac YouTube Downloader to me.

As a Free Mac YouTube Downloader, it can automatically detect the YouTube video files from the YouTube web pages you have opened and download multiple files at a time. YouTube downloader for Mac is a totally free YouTube video downloader for Mac, because if you don't want to convert downloaded videos to your mobile players, you don't have to pay for it.

But you need to pay for the conversion function, converting youtube video to other format video.

I think it would be useful on downloading youtube videos and share it here.

p.s. I just use it to download youtube video, because I have gotten a all-powerful video converter. LOL

And sorry for that I'm not sure if the forum is right place to post this info...
