1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
It is good to know how Disk Utility (spelled "disk" by the way, not "disc") works, but it might also be good to know what you're trying to do. While Disk Utility is extremely unlikely to do any harm, if you are trying to speed up video you may also find it doesn't achieve much (unless your computer is really in a bad way). Is this what you are trying to do, and what makes you think it needs it?
On these forums (and presumably elsewhere) "disk" usually refers to a hard drive, "disc" refers to an optical medium. Wikipedia [http://en.wikipedia.org/wiki/Disc] suggests common usage adheres to this pattern.
"Disk Utility" is proper noun (as observed by another poster) so if you're searching for it you have to look for it however Apple decides to spell it.
