If you want to download use greasemonkey/userscripts or if you use some program like download all or flashget or something like that then just add the fmt’s to the end of the end of the video’s URL and press enter, then download.

YouTube’s three highest quallity formats are 18/22 and 35

The highest Quality video’s is obviously HD and use: fmt=22, if the video is actually HD you would see a red HD symbol appear on the flash player next to the button for fullscreen.

The second best quality is: fmt=35, third best is: fmt=18, these are considered to be HQ, High Quality, however this on some videos is not actually true it seems to make fmt=18 better than fmt=35.
On HQ you would see instead of the red HD, you would see a red HQ
