If I embed a youtube on a page, is it shown complete with the advertisement that often appears at the start of a youtube, or at the start of a you tube? If so, is there some way to get rid of the ad. Technically, it ought to be possible as on the Apple, I use an application, clea.nr YouTube (TM). However, is this extraordinary, or can this technology be duplicated on a custom basis for a site?

Thank you in advance for any help.
