dual layer DVDs

Hello everyone: Just purchased SuSE 9.3 and want to make a copy of the 64-bit DVD. However, instead of the double-sided DVD that came with SuSE 9.1, the DVD in SuSE 9.3 is a dual-layer flavor. Is there any programs that will allow me to copy this dual-layer DVD? I've had a look at the K3B site and I know it can copy conventional DVDs as I've done it myself. However, I can't seem to find any info that confirms K3B will burn the dual-layer DVD. My burner can handle this format, so it is a question of finding the right software to do the job. Any help greatly appreciated. Cheers, Mike
