[Blomquist, Niklas]

Hello All,

I having some problem to burn Audio CD from MP3.

I can burn normal CD, but If I try to brun Audio CD (with gcompust) it
refuse to pad the CD. If I use Gnome Toaster, i'll get the error: 

cdrecord: Track 1 has unknown length
cdrecrod: Cannot open new session

Please help!!
