Nerocmd multisession

Hey

i have some problems with creating / continuing multisession on NeroLinux with the Nerocmd:

nerocmd --drive=“Atapi BD B DH4B1S” --write --bd --udf --tao --close-session --verify --data …

that’s how i start the multisession disk, but if i try to add more data with:

nerocmd --drive=“Atapi BD B DH4B1S” --write --bd --udf --tao --import-udf --close-session --data …

Nero tells me always that the disc is not empty (how right :P) but the only option that i have are:

“Erase disc Eject disc >Cancel<”

thx 4 help!!
