Youtube Downloader HD
You will get your favorite clips simply and quickly without advertisements, time limits or registration. With Youtube Downloader HD you also have the option of choosing between four preset output formats (FLV, AVI, MP4 and AVI HD), so that you can play back the resulting file in the portable device you want.
Finally, Youtube Downloader HD supports Unicode. That means you can also download videos with characters that are not the common ones (mainly from an Oriental origin).
