I just bought an LG Electronics WH12LS39K M-Disc 12X Internal SATA Blu-Ray Rewriter that I'm running under 64-bit Linux Mint 12 (Gnome desktop) and K3b since that seems to be the only Blu Ray capable burner software in the repository.

The normal Asus DVD burner works fine as does VLC for playing media.

The computer, OS and K3b all see and identify the burner correctly however, when I try to burn a project the software treats the burner and disc as if they are just a standard DVD burner with only 4 GB of capacity. The strange thing is that I can click on the loaded drive in the upper pane and it properly shows the disc capacity as 25GB. But if I try to create a project, it tells me I'm over the disc's limit of 4 GB!

Am I missing a codec or something? I've searched the Web but haven't turned up anything applicable.

Thanks for any help you can provide.
