1. There is no Media Jukebox Gold. There is a Media Jukebox Plus. I'm not nitpicking here, I'm just clarifying that we're talking about the same product. For some reason people confuse Media Jukebox with Music Match Jukebox a lot.
2. The 99 limit JohnT is talking about isn't a limit set by Media Jukebox. It's a limit set by the Redbook Audio Format standard (if I'm understanding him right).
3. When he asks what version of Media Jukebox you're using, he means, what's the version number? 7, 7.1, 7.2, or one of the beta versions of 8.
4. ASPI is what Media Jukebox uses to communicate with your CD-RW drive. Updating it to the newest version will insure that you have the most up-to-date and compatible version. It may or may not fix your particular problem.
5. Did these particular CD blanks work when you burned with Roxio? Many players have problems with CD-RW's and even a lot of CD-R's. My Sony DVD player won't play CD-R's at all, for instance, but my car stereo will work fine with them.
