    CD/DVD burners have two lasers... In your NEC, one of them has burned out or warped. The other laser is still good

    If it is that old, chances are that there is a speck of dust on the burner lens. I could shoot the clown that invented looky-uppy lenses.

    You have to be very careful on how you clean a laser lens. Try using a very soft brush then use a commercial camera lens cleaner. Sometimes the laser lens can be refocused by adjusting a small pot (control) on the connecting cable of the laser assembly...

    With the low cost of CD writers these days, trying these things is not really necessary. They don't work that well anymore. These things worked better on the first generation lasers though

    So what brand burner did you order? Now that Plextor is not making drives anymore and Benq went bellyup. I am considering the LG's. fortunately though I have a stash of Plex 760a Burners still in the box unopened. so having to buy a new burner sometime soon For my personal machine is not a worry. but I do need to replace a Plex 716A that went bellyup with the rest of the machine during a storm.

    LITE-ON Black 20X DVD+R 8X DVD+RW 8X DVD+R DL 20X DVD-R 6X DVD-RW 12X DVD-RAM 16X DVD-ROM 48X CD-R 32X CD-RW 48X CD-ROM 2MB Cache SATA 20X DVD±R DVD Burner With 12X DVD-RAM Write - OEM $32.99

    I bought a bunch of cables for customer builds
    with this oem you need your own cables
    I would not mess with the nec dvd burner just let it slowly break down
    since it still burns and the other drives can read what it burns it will be one of the product burners till it goes completely
    on another note memorex sent me 50 16x's free for complaining about some retail dvd's in jewel cases
