I recently conducted a test using Ubuntu 10.10 (Maverick Meerkat),
Brasero 2.31.92-0ubuntu1 and an external Blu-Ray Multi Burner. The media
tested was Memorex 4x 25GB Single Layer Recordable BD-R.

$ wodim --devices
wodim: Overview of accessible drives (2 found) :
 0  dev='/dev/scd0'	rwrw-- : 'MATSHITA' 'DVD+-RW UJ-857G'
 1  dev='/dev/scd1'	rwrw-- : 'HL-DT-ST' 'BD-RE  BH10NS30'

$ lsusb

$ uname -r

Disk Type Recognition Test - PASS
>From what I can see in my test, using 10.10, the following issues have already been corrected:

-Inserting a BD-R disc causes nautilus to recognize it as "Blank Blu-Ray R Disc"
-Brasero recognizes the disc as "Blank Blu-Ray R Disc: 23.3 GB of free space"

BD-R Burning Test - FAIL
-Burning dialog has a setting for speed. It offers 8x although the maximum for the disk is 4x. Capabilities of disk are not probed.
-Burning dialog has a "Options" section is blank but still has a title. Expecting this is where you would have simulate options etc.
-Burning ends up with a failed attempt before starting the burn, resulting in one of the following two errors.
     - "Merging data is impossible with this disc"
     - "An internal error occurred"

Attached is a combination of brasero logs as debug information. These
are the output of 'brasero -g' and of 'brasero --brasero-media-debug'
while testing the recognition and burning.
