My CD burner is often burn DVD + R?
I went to buy DVD + R and I put in my CD and not recognize them. They are Memorex DVD + R 16x 4.7GB 120 min DVD + R and my burner is a HL-DT-ST RW / DVD GCC-4482B Mini DVDSoft I tried WinDVD and many other programs do not work, please help.
Verify that the recorder DVD can handle DVD + R, DVD-R no
