Burning multisession problem

Hi, I've bought the cd recorder LG GCE-8520B and I'm trying to use it in multisession. I can't understand the behaviuor of mkisofs...I mean: at first creation of ISO9660 image everything works fine, but at the moment I use the command: mkisofs -r -J -C `cdrecord dev=0,0,0 -msinfo` -M /dev/cdrecorder -o immagine2.iso /opt/TEST I have always to eject and re-insert the cd to have the new image. When this happens mkisofs exits with error: <mkhybrid: Success. Read error on old image> Is there a way to resolve a such problem? Thank you, Fab :) --------------------------------- Yahoo!
