Yes, that will work. However, you will not be able to get the video title with the # symbol. That URL is a redirect as far as AME is concerned, so it will only get the title of the redirect page.
You can have one definition to parse both URLs, if you want. Just change this to the Regular Expression:
Code:
http://[\w]+\.youtube\.[\w]+/watch\??\#?v=([\w-]+)[\w&;=-]*[\#t=]*([\d]*)[&;10shdq=]*
