k3b does not recognise a valid blu-ray ISO

[Alistair Buxton]

I am attempting to write a blu-ray video ISO authored using some windows software, because this is not currently possible under Linux. k3b does not recognise the ISO, saying it is unusable. I have burnt several versions of this ISO using brasero with no problems, and they all played fine in a real blu-ray player.
