Nero doesnt retrieve CD-Text


I wonder if NeroAPI supports all implementations of CD-Text. I burned a cd with cd-text and the NeroAPITest tool retrieves it, as it should. But if i try to get cd-text from a cd I bought, it finds no information. The cd has cd-text, i verified that by using my car-audio system. The CD-Text logo is on the disc, too.

What is funny is that if I use the Nero Info Tool it shows me the artist and album name. So i guess the tool doesnt use NeroGetCDInfo. But what else? Any ideas?
