I purchased a CD-R/RW DVD-R/RW drive for my Sony laptop. The TEAC drive functions as a CD-R/RW properly using Easy CD Creator (ecdc ). It will not write a DVD-R using ecdc, it says I have the wrong media type. am using a DVD-R disk, could I be needing a DVD+R disk ?? What is the difference ?? Someone told me needed Nero 6. The DVD drive will not play DVD movies as well.
