I've had this Vaio Laptop for 3 years now. All of a sudden, it won't play a dvd. I'm using a WinDVD4 for Vaio. The message, "Create Overlay Failed" comes up and asks to change screen resolution. I have done that without success. Will try any suggestions. Please know that I am not literate with these machines. My email address is rdkline1@aol.com
