IMPORTANT NOTE for 6.0 users! Newer Linux kernels have ridiculously low default memorylocked resource limit, which prevents privileged users from starting growisofs 6.0 with "unable to anonymously mmap 33554432: Resource temporarily unavailable" error message. Next version will naturally have workaround coded in, but meanwhile you have to issue following command at command prompt prior starting growisofs: * if you run C-like shell, issue 'limit memorylocked unlimited'; * if you run Bourne-like shell, issue 'ulimit -l unlimited'; HTH, Chris
