After i read tracks xcdroast records them in /tmp/imgcd and creates the image...
Then i go to Write CD and click on write cd to start burning...

The pop-up window comes up and says:

Calling: /usr/lib/xcdroast-0.98/bin/xcdrwrap CDRECORD dev=0,0,0 gracetime=2 fs=4096k driveropts=burnfree -v -useinfo speed=30 -dao -eject -pad -audio "/tmp/imgcd/track-01.wav" ...

cdrecord: ISRC '2@-400-05-00322' contains illegal character '@'.


Any idea what is wrong?

Well i solved the problem by installing new version of xcdroast.

When i hit write cd it asks wetter i want or not to clean the image of illegal characters and if you hit yes it goes ok...

Don't know why..
