Can't download youtube clips to desktop with Chrome

I like getting youtube files songs for my Real Player but I can't do this with chrome only FF allows me to get clips to desktop, Chrome does not show the download button, this has been true with all versions of Chrome, on 3 different computers I run and FF is the one I use for getting Clips, IE also works but I don't use that.
Solutions??
Thanks

 

In Chrome, click the Wrench icon, then "Settings" > "Extensions" > "Get more extensions ".

In the "Search the store" box, type in "youtube video downloader" (without the quotes) and press [Enter].

Select which one you want from the list.
