Why no setting of layer break for DVD-Audio?

[fchef]

Hi everyone, I have created myself a dvd-audio project Audio_ts only (Video_ts is empty) which has size 7GB. I used imgburn twice,first to create an iso in hard disk and then burn, and write mode directly to burn the contents to a Varbatim (MKM-003) DVD+R DL . I was expecting to see that window to choose layer break but in both cases it did not appear and imgburn proceeded with burning.

Have I done something wrong or imgburn does not support this dvd-audio layer setting?

Thanks in advance

I don't know enough about DVD Audio to implement anything like that for it.
