I tried to burn 25 Gb BR-R (just as data disk, no fancy video) but discovered that k3b as shipped with TDE: R14.1.3 does not allow me to pick BD-sized project.

Is there chance to see "on the fly" (due to hdd space constrains on my end) BD /udf 2.01 mastering added to k3b?

For now I used imgburn under wine, but cdrecord seems to know how to deal with BD drivers and disks:
