Reading a CD but with skipping suggest either a dirty lens or a failing laser.  I would first clean the lens using a cotton swab and some alcohol.  Be gentle as the lens is supported by small fine wires only.  Next, clean the rails that the laser assembly rides on.

What happens is this:  The laser will fire and try to detect the CD/DVD.  Assuming that it can see the disk (in your case it can), then the disk will spin and the optics will attempt to read the index track.  It looks like the index is being read for the CD but not in the case of the DVD/Game.  DVDs and games require higher laser power to be read.  A sign of laser failure is to read CDs but  not DVD/Games.  Sometimes cleaning resolves the problem.

The skipping can be the laser as well. But most often, is dirt on the rails.  The lens will move enough to read a few tracks before the motor kicks in for the gross movement of the entire assembly.

Try cleaning and report back with the results.
