I am trying to burn the live CD, but I keep receiving this failure:
Boot CD - BurnAware Free [28/06/2009]
D: SONY CD-RW CRX835E KPK4
[19.17.32] Preparing compilation
[19.17.43] Processo di scrittura fallito (Power Calibration Area Error.)

imgburn FTW :)
Ok thanks,
this happened also with other softwares, anyway I am trying the one you suggested.
I don't know anything about BurnAware Free so I can't really help you in that respect.
I can however, recommend a free ISO burning utility called ISO Recorder, its always worked for me.
