Hello guyz,
About Farah's question it's easy:
1-first you should sign up and create a youtube account by choosing
sign up2-then
sign in and whenever you watch a video you can click
save to favorites and it'll be automatically saved to your list
3-then you could check your favorite videos list by clicking on the link
my account which can be easily seen on the upper left handside of the screen (needless to say you have to be singed in before accessing your account)
4-and then you'll find
favorite videos on the left
But I think Yezen's method is much better specially if you have fast connection... I tried it and didn't work
I've downloaded both programs and extracted them and when I pasted the link into the downloader and after pressing grab this happened

So Yezen, what seems to be the problem ?
And one more thing, could you tell me which program converts flv to mpg,avi,wmv...etc so that I can play the video on other media players
