You need to try to clean the laser head and the transport. To do this you will need cotton swabs, isopropyl alcohol and small cans of lithium grease and compressed air.. Open the up the compartment that the dvd discs are placed. In the center of the compartment you will find the spindle and a laser transport. In the transport you will see the laser head. Take a cotton swab and put a small amount of alcohol on the tip. Rub the tip of swab gently across the head of the laser. Do this until the head look bright and shines. Use the other end of the swab to dry the excess moisture off the laser head. Take another swab and use a small amount of alcohol on the tip and go around the transport device cleaning the dust and dirt from it. Use a small can of compressed air to blow away any dust and dirt in the compartment. Once the laser head is cleaned and the transport is cleared of dust and dirt, Move the transport to the outer most point and bring it back in to its closest point. Do this several times. Do not apply to much pressure while doing it.If you find ruff and uneven action. Clean the areas of problem and return the transport action to smooth and easy operation. If still not smooth and easy. Take another cotton swab and use some lithium grease in very small amounts to lubricate the transport rails. Again move the transport back and forth to lubricate the laser transport. This should return the transport to normal action. Now play a music cd to calibrate the laser head . Let the cd play through a couple of times. After doing this you can now try a dvd disc and it should play normally. If it still does not play correctly, check the spindel to see if it is loose. If this is the case use a drop of super glue to tighten it up. Let it dry completely and try the disc again. It should work correctly. If you are still having a problem.You either have a problem with the laser itself or the drive motor. The drive motor problem would usually be noticed on the playing of the cd. The laser head and the motor can be replaced if this is the problem. You can find more information on how to do these repairs on you tube. Put cleaning and repairing portable dvd players in the search engine and it will bring up videos on how people have done these types of repairs. I hope this information will help you with your problem.
