आप go to यूट्यूब go to a vid u like and look where it says ADRESS या WWW.YOUTUBE.COM.and click your left button.if आप did it right it will say cut copy paste.if it doesnt click the other button.always copy.then paste.
well, the way i do it is first go to यूट्यूब (it doesn't seem that आप can do this with other websites) find a video आप like there. then under the vid it should have a button that says share click it then it should have a highlighted bunch of letters right click it then copy then click 'embed a video' back here and paste. simple.
here's a बिना सोचे समझे vid that i embed just to दिखाना it works.
