Hey folks first timer here. If not posted in the right place please place correctly. I have a SONI Vaio VGN-NR430E and I'm running Windows 7 Home Premium. My DVD player a Matshita DVD Ram UJ870QJ ATA Device will PLAY a DVD movie but will not play a music CD or read a program CD such as  "Tech Spark Studio" . This is a Polaris Manual CD, or any other programming manuals that allow me to use new items on my laptop. I've tried to update the DVD drivers but it says I have the current update, also the Device manager says this device is working properly ! HELP I hope I've explained my situation correctly and given you enough info to be able to help me! Thanks in advance. Sincerely ;   cougar.
