How to download youtube videos onto my mac easily, and for free?

I would like to attached videos to my email but the videos are unable to be downloaded completely.

how can i download a youtube video?

I check Audio in Settings but no audio downloads from youTube.  I have tried different codecs, but its always the same.

I have no experience on Blu ray files and disk yet. I haven't bought a single movie in blu ray.
So I would like to ask, do I need a special media player to play blu ray movies downloaded from the internet? How about from a blu ray disk inserted into the disk drive?
