How to set start and end markers for youtube video

To set a start and end time for a youtube video, we use a url in the format:

https://www.youtube.com/v/VIDEOID?start=0&end=10&version=3

Where, VIDEOID is your video ID (obviously) and your start and end time are in seconds.

* You can use either the https://youtube.googleapis.com or http://www.youtube.com url

* If the version=3 parameter is omitted, the video starts at the correct place but runs all the way to the end. From the documentation for the end parameter I am guessing version=3 asks for the AS3 player to be used

* Here are the full list of parameters supported by the API:
