Even burncd ought to be able to burn a standard CD-R or a blank CD-RW...did you forget to use "fixate" or DAO burning mode? cdrecord ought to work also. > And a (sort of) related question, will growisofs write double or > dual layer DVDs?

The most recent versions of growisofs supports burning dual-layer DVDs, both DVD-R and DVD+R. If you're trying to burn things larger than 4GB, the program may not be able to generate the .iso image dynamicly on the fly from a directory tree, so if you have problems, create the .iso image as a file first and then burn it separately. I haven't heard about this problem happening (often?) under FreeBSD, however: * 5.20: [ ... ] * - DVD+R Double Layer support; * - -use-the-force-luke=4gms to allow ISO9660 directory structures * to cross 4GB boundary, the option is effective only with DVD+R DL * and for data to be accessible under Linux isofs a kernel patch is * required; * - more sane sanity check for -use-the-force-luke=tracksize:N; * - -use-the-force-luke=break:size to set Layer Break position for * Double Layer recordings; * - speed verification issue with 8x AccessTek derivatives addressed; * - -use-the-force-luke=noload to leave tray ejected at the end; * - allow to resume incomplete sessions recorded with -M option; * - Layer Break position sanity check with respect to dataset size; * - #if directive to get rid of sudo check at compile time with * 'make WARN=-DI_KNOW_ALL_ABOUT_SUDO'; * 5.21: * - Linux: fix for kernel version 2.6>=8, 2.6.8 itself is deficient, * but the problem can be worked around by installing this version * set-root-uid; * 6.0: * - fix for DVD+R recordings in Samsung TS-H542A; * - DVD-R Dual Layer DAO and Incremental support; [ ... ] -- -Chuck
