I recently upgraded my operating system from windows 98 to XP Pro, and now my Pioneer 106s DVD ROM will not play properly. Do I need to download new firmware or something? And if so, where do I find it, and is there a specific procedure to follow? The O/S change did not seem to affect my CD RW, as it appears to be working as before. I am currently using Driver Version 5.1.2535.0 - van._
