Tips on burning to Bluray (BD-R) media under Fedora 20

[Steven Ulrick]

Hello, Everyone
I just installed a new Asus Bluray drive/burner and everything seems
to work fine so far except for one thing: I can't burn to Bluray
(BD-R) media using K3B.  K3B detects my media correctly, even tells me
in the burn dialog that I have an "Empty BD-R  medium" in the drive.
I am trying to burn 21.4 GiB to a disc that K3B automatically detects
as having  a capacity of 23.3 GiB.  So, things look good so far...
Then I do the following:
1. "Open the burn dialog for the current project"
2. Click the "Burn" button.
3. This soon results in this interesting message:
Found medium: Empty BD-R medium
Please insert an empty medium of size 21.4 GiB or larger into drive
ASUS BC-12B1ST b (/dev/sr0)
Load   Eject   Cancel

As you probably assume, clicking "Load" just redraws the above quoted
error message...

Right now I am using mkisofs to make an image of the same 21.4 GiB of
data that I want to test this new drive with.  We'll see what
happens...

Oh yeah, this new drive rips CD's perfectly, as well as burning to
single layer DVD media.  I don't have any dual layer around to play
with.

Thank you for your help,
Steven P. Ulrick
