If I embed a youtube video for streaming and the video is 6mb in size does it mean it takes up 6mb of my bandwidth to play?
Nope, takes up 100% of YouTubes bandwidth, the only bandwidth that is "spent" on your site is downloading the page. Hope I've helped
That's right you are not affected one bit. It's the same idea as if you took an image and linked it from my site. I would lose say 100kb. But if you hosted that image you would lose the 100kb when someone viewed the page. The videos are streamed from YouTube so it wastes 0 of your bandwidth. Skinny
