I’ve been using the Memorex 80 min CD-R for a couple of months and it worked fine (minus the speed problem - burning at 16x is fine, but at 8x i get noise) and will play on the car stereo. The newest batch, however, refuses to work on the car stereo (JBL). After getting DVDInfoPro, I’ve discovered that the old batch (works) was made by CMC (an inferior company?) and that the newest batch (doesn’t work) was made by ProDisc (isn’t this better?). So what’s going on?
