Here is my problem. I have a 4x2x32x cdrw. It will read most cd's fine, unless it is a store bought music cd, in which case it won't read it. Also, when I burn a cd full of songs, say 20, at the end only 5 or so will actually be usable. Any help with either of these problems would be greatly appreciated. I have a duron 800, 256 ram, 20 gig hd, winxp, Nero Burning rom, and a 40x cdrom. Thank you in advance for your help.
