The best way is to buy or borrow a cleaning disk. Load the disk into your player and it will do the rest.
This could be a DVD drive issue. You could try and clean your drive with a dvd drive cleaner.
No, a dvd device is either a DVD player, or a DVD drive on a computer.
There is no hard disk drive in a DVD player. So nothing will go wrong.
Buy a lens cleaner. They do work.
No.
yes u can do so
it depends. are you using a DVD/ CD player? or are you using just a plain CD player? if ur using the CD player, it wont work because it doesn't have a screen. if your using a DVD/ CD player, it will work just fine. A DVD will not play in a CD-only player -- even a CD-ROM drive that does not have DVD hardware built in. The stepper motors and lenses for a DVD-ROM drive are far more precise than a CD drive, and the CD drive cannot physically read the tiny information on the DVD surface.

You put it in the drive of a DVD player and then watch it. Of course its not quite that easy. Unless it's a portable DVD player you have to have a monitor to play it with.
Depending on the model and features of the DVD player, some can play CD-RW and other formats. The printed materials supplied with the DVD player will state what formats the player can read/play.
This is just the way it is. Most DVD players will not read all formats.
A clean installation is a installation where the hard drive is reformatted and windows is installed fresh from the DVD or CD it came from.
