Since we enabled annotations on embedded videos, the most consistent
piece of feedback has been the request for the option to disable
them.

Here's how you do it...

To disable annotations on a video you'd like to embed on another site,
just add the following parameter to the video's embed code:

&iv_load_policy=3

Example:

<object width="425" height="344"<param name="movie" value="http://
www.youtube.com/v/SDekCNYePQ8&hl=en&fs=1&iv_load_policy=3"></param><param
name="allowFullScreen" value="true"></param><param
name="allowscriptaccess" value="always"></param><<embed src="http://
www.youtube.com/v/SDekCNYePQ8&hl=en&fs=1&iv_load_policy=3"
type="application/x-shockwave-flash" allowscriptaccess="always"
allowfullscreen="true" width="425" height="344"></embed>/object>

NOTE: By adding &iv_load_policy=3 to the video's embed code, the
annotations will be off *by default* in the embedded video, but it is
still possible for a viewer to turn them on via the menu in the
player.
