anda go to youtube go to a vid u like and look where it says ADRESS atau WWW.YOUTUBE.COM.and click your left button.if anda 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 youtube (it doesn't seem that anda can do this with other websites) find a video anda 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 acak vid that i embed just to tampil it works.
