Should I assume then that failure > was because growisofs reserved more spare space in its formatting > than I allowed for by my image size? growisofs formats blank BD-R to the default size, which is listed with format code 00h, unless you use option -use-the-force-luke=spare:none which will leave the BD-R unformatted and write with full nominal speed and without checkreading. If you cannot get the GUI frontend to using this option, then you may format the BD-R by dvd+rw-format to the smallest possible size. (A bold try with -ssa=16m or -ssa=128m should not kill drive or media but rather succeed, or fail and leave the BD-R blank. -ssa=256m should work in any case.) This also avoids the little bug at the end of a growisofs BD-R run. > in reading about xorriso it's really > just for ISO formats correct? Currently no UDF, at least. (Bootability leads quite far off ISO, but not nearer to UDF.)

We have to distinguish media level formatting and filesystem format. In the case of DVD and BD video, the medium formatting is not decisive, except that some media just cannot be written unformatted. DVD and BD format compatibility is clearly only about the filesystem, because there is only one readable sector size with these media. (On CD there is half a dozen sector layouts. From 2352 bytes audio to 2048 bytes data.) > # xorriso -outdev /dev/sr0 -list_formats > ... > libburn : SORRY : Cannot open busy device '/dev/sr0' : Device or resource busy Some program holds the device file open with flag O_EXCL, which has a special meaning on Linux device files. It indicates that a drive is mounted and shall not be written directly. We burn programmers joined that club. For us it means that it shall not be touched at all. (Touching a CD burn can spoil it.) What do you get from mount | fgrep /dev/sr0 lsof | fgrep /dev/sr0 > udftools will create an image up to 2.01, Hasn't udftools been superseded by kernel UDF ?
