I have a NEC NR-7900A burner with XP home. When I first got the computer it had roxio ezcd basic and musicmatch on it.I used the trial version of music match to burn 2 mp3 cds.They worked fine but from then on I haven't been able to get a mp3 cd to play on a mp3 player. I've tried two different mp3 players so I kmow its not them. I've tried 3 different programs(Roxio, nero5590, Musicmatch Plus) all installed one at a time. I've even had my burner replaced by DELL because thats what they thought it might be, but it wasn't. I've tried CD-R's and CD-RW's but neither worked. I've even tried re-installing XP, But no luck. Regular cds burn and play fine. The mp3 cds are readable and playable by my computer but not the mp3 players. Any answers?
