I guess u all know
www.youtube.com where you can watch a lot of videos but u can't download them !
Well if sometimes u needed to download one of them u just have to go to:
http://www.dubayou.com/mytube/
Copy the link to the box and click rip it ...
Then u will have to download it by right-clicking on the"flv format" .. save target as ...
By then u will have the video on ur pc but in flv format (smth like mpg or avi..)
U should have an flv reader or any converter
If u have any questions don't hesitate to ask me ...
