I have got sony dvd writer. it used to read data dvd's before. it still reads video and audio dvd's. now when i put a game dvd i used b4 it says 0 objetcs inside. and even i bought a windows original flight simulator X . when i put it in it says 0 objects. when i put the same in friends pc it reads. i also does write data dvds. just doesnt read. so what can be the problem. the data dvd i just made the rom does read it. so what is gopin i dont know a bit. it reads the data dvd i just burned now and doesnt read other data dvds.
