"None of the sites offer movies legally  which streams movie online except Netflix ."

Are you high or something Nepaliworks? Rajshri.com is 100% legal because it carries movies produced by Rajshri productions. Erosentertainment.com only offers movies by erosentertainment. Check nai nagari hawa taal ma guff hanne? 

Also the youtube link I shared is for Bollywood movies that were uploaded by Youtube, not public users.
