Hi, firstly: Your trouble has nothing to do with image content. You may burn what you want as long as it fits into the number of 2048 blocks, which the medium offers.
It might be that GUI frontends are still not ready for BD media. The halfways modern backends (growisofs, cdrecord, libburn) support them. I helped to beef up xfburn version 0.5.2 so that it accepts BD media and makes use of the according libburn capabilities. On the command line there are: dvd+rw-format /dev/sr0 growisofs -Z /dev/sr0="$HOME"/my_image.udf or growisofs -use-the-force-luke=spare:none -Z /dev/sr0="$HOME"/my_image.udf or cdrecord -v dev=/dev/sr0 "$HOME"/my_image.udf or cdrskin -v dev=/dev/sr0 "$HOME"/my_image.udf or xorriso -as cdrecord -v dev=/dev/sr0 "$HOME"/my_image.udf The drive address is assumed as /dev/sr0 here. You may get a list of accessible optical drives by xorriso -devices which might say something like 0 -dev '/dev/sr0' rwrw-- : 'TSSTcorp' 'CDDVDW SH-S203B' 1 -dev '/dev/sr1' rwrw-- : 'HL-DT-ST' 'BD-RE BH16NS40' (I.e. i'd better use /dev/sr1 for BD burning.) If you want full nominal speed on formatted BD, use cdrskin or xorriso -as cdrecord option stream_recording=on No checkreading and no bad block replacement will happen then. If you want formatted BD-R (for slow checkreading): dvd+rw-format /dev/sr0 or cdrskin -v dev=/dev/sr0 blank=format_defectmgt or xorriso -outdev /dev/sr0 -format as_needed These will get you the default size. There are options to vary the formatted size, too. > I'm trying to understand where is the problem and should this be > submitted as a bug report or a feature request and to whom.

Well, we have to send data in chunks of at least 2048 bytes, better of 64 KiB. The communications protocol between burn (backend) program and drive is defined in SCSI/MMC. BD are mentioned since MMC revision 5. > It is also stated on > dvd+rw-tools' web page that growisofs depends on cdrtools, namely > mkisofs, Only on mkisofs, not on cdrecord. growisofs is its own burn backend. Hard to surpass with DVD and with only a little flaw about automatic formatting of BD-R. (Above examples work around it.) > I speculate that in this case I don't need mkisofs because > I already have (UDF 2.5) file system in the image and I'm "merely" > trying to burn it on a BD-R DL disk. Right? Yes. > K3b claims that it supports Blu-ray Then your problem should be considered a bug. At least if you manage to burn by any of the above command line examples. > who gets the job done and how? :S Choose one of the programs mentioned above. The command liners have nearly no dependencies. xfburn might drag in half of Xfce. (I can offer a frontend demo named xorriso-tcltk http://www.gnu.org/software/xorriso/xorriso-tcltk-screen.gif which depends only on Tcl/Tk.)
