Writing info to CDs using Waveburner

Hi. Hope some one can help. I'm burning CDs using waveburner on my imac os x and have included ISRC codes as well as track names. I have checked the boxes and burnt the disc. The cd plays ok but does not seem to include the titles or ISRC numbers. I have checked this by opening the cd in iTunes and also by importing the data from the cd back into a new waverburner doc. Neither lists the data I am trying to include on the discs.
Would appreciate some advice. Thank you
