I just purchased an MP3 player for my car, and burned an MP3 CD from iTunes, only to find out that it would not play since iTunes burns the CD in Mac OS Extended format and the car stereo would only play ISO 9660 CDs.
I wanted to keep all the playlists that I had and did not want to move, by hand, all the MP3s into a separate folder to burn in Toast (the Export Playlist to Toast 2 AppleScript from Doug's AppleScripts for iTunes took way to long to create). Suddenly, I had en epiphany (I thought it was just gas…); why not try dragging the songs directly from iTunes into Toast? I opened Toast, selected ISO 9660 as the type of CD that I wanted to create, and then clicked the "Select" button to open a window where you can drag and drop files into. I switched back to iTunes and then selected the songs (not the playlist) I wished to burn and dragged them into the Toast window (ISO 9660) and voila! It worked.
Note: You may receive a warning from Toast that some of the file names are not ISO 9660 compliant. In the ISO 9660 window that opened when clicking the Select button, click on the Settings tab, and in the Format menu, select CD-ROM and change the Naming menu to Joliet (or the MP3 player may not recognize some songs). Then, in the Files tab, look for all the file names that have "!!!" to their right, and you will have to change those names, or or the MP3 player may not recognize some songs. It may be as a result of a character not used in Windows ("?" or "!"), or the file name may be too long (it looks like 64 charcters is the limit). It also seems that Toast is using the MP3 tag as the file name, instead of the Mac OS file name.
