There's another way to save Youtube Clips... If you're using Mozilla Firefox you can simply download one of their extensions from their site, the "video downloader", after you've done this i believe you'll get a confirmation telling you that you've installed the new extension sucessfully or so, if not, there's no big deal cause he probably installed it anyway...
🙂 A new icon should now be visible on the lower right corner of your screen, that's a shortcut to "video downloader", this means that when you're on a specific website who has mainstreams clips such as Youtube, you can click on it, in the window that just popped up, you need to right-click on "download link" and select "save link as", then name the video. The video must be named as flv format, in other others words, the name of the video has to end in ".flv"
For example:
"Tickling Viviana.flv"
After the video finishs downloading to your hard drive, the only thing that you need to do is to convert the file you just downloaded using an apropriate software that can convert flv into wmv, avi, or another format of your preference... I use the "Total Video Converter", it can convert various types of formats into divx, xvid, and even Sony PSP format! The only bad thing in using this method is that this software isn't freeware... I hope you understood my english, and i can only hope that this was of any help at all to anyone.
