Downloading High Quality Youtube Videos

For Downloading Youtube Videos I recommend using http://keep-tube.com

It has a nice interface and lots of different options. You can choose Mp4 file format in High Quality for downloading ...

For example this is the download page:

http://keep-tube.com/?url=http://www.youtube.com/watch?v=HZT3ykAkLGg

for this video:

http://www.youtube.com/watch?v=HZT3ykAkLGg

Of course you can.Here, I found efficient one with good quality,it's totally free:

http://www.download-streaming-video.com/free-youtube-downloader/#137

you can use ClipNabber - download videos from youtube

after you paste in the url just download the link that says MP4 for high quality, or the FLV one for lower quality

I use ant toolbar in downloading videos.
