Yes, you can too :) But sometimes Youtube Downloader doesn;t allow “certain” videos to be downloaded..
I’ve never once had the problem with this downloader...
See “Free YouTube Download” (on right)

HOWEVER, be careful selecting the “options” (check boxes, etc) when downloading the program. Take it slow and think carefully. Otherwise they’ll add various stuff on your computer.
