Due to new cookie regulations in EU it is now (in certain countries) required to ask people to allow cookies before we can display "normal" youtube videos to them.
To avoid this youtube is offering a nocookie version of videos (youtube-nocookie.com).
I have updated the YouTube embed regex to now use YouTube's no cookie domain (youtube-nocookie.com) for all YouTube video embeds.
This means YouTube videos embed on these forums (and ski.com.au) no longer drop cookies and track your viewing history.
This also means you can use the no cookie domain URL's as the embed string;
Regular YouTube url's will continue to work as usual and the resultant embed output will be cookie free.
