Query: I am on my third because they keep breaking

I was expecting a quality Sony product when I bought this. I have another sony DVD player that I have been using for about 3 years without any problems. This unit is another story.After 4 months of use, the player stopped working with DVD/RW disks. A few days later, manufactured disks stopped working, now a few days later, no DVDs will play on the unit.I am so glad I got an extended warranty, because I am going to go and pick up my third new unit today for another 4 months of usage before the inevitable failure.
