Hi friends
I found this great online tool which i would love to tell u about it , this is http://vixy.net/ . Just go there , type the youtube url of the video . Select the format from options like Avi,MP4,MP3,3GP and mov . Click Start . The site will download it and convert it into the desired format . And then it will give you the link to download the video in the desired format . No loss of quality at all . And who said Japaneses are only good in Playstation ?
