DVD I want to replace cd player with DVD player.Is it possible?What to be done and how much is the rate?

Hi,
I don't mean to disagree with my associate, but DVD players for R series (or T, A, etc) can be found for less than 20.00 US (Ebay is a good example)
For that matter, we've got at least a dozen at our shop which we sell for 25.00
Installation is very simple as well, just pop the old drive out, put the new drive in.
Good luck

Sure it possible, check these links:
