I bought Verbatim BD-R discs for use in a Samsung SE-506 Blu-Ray writer. When I place the disk in the writer, ImgBurn reports that the capacity of the disc as 25GB, which is correct. But when I select a 25GB ISO and specify the target as the Verbatim 25GB BD-R disc that's in the Samsung SE-506 Blu-Ray writer, I'm told that the disc is just 13GB and that the 25GB file will not fit. I can't send a log file because I never start the process. Any idea what I've set incorrectly? Thanks!
