Drive is Samsung CDRW/DVD SM-348B. I have burned music to Memorex CD-R using windows media player 9 on windows 2000 pro. When I play the cd, the songs seem ok, except there is intermittent, short, extra garbled (sounds kind of like a sci-fi sound effect) sound. I have stored the cds for a few years; computer is 5 or so years old and I believe the drive is the same age. What is wrong? Thank you much.
