Looking at the DVDInfoPro output, it shows that the MID code speed is 4x, which verifies that it is 4x media.
However, the Write Descriptor speeds are only 2x, 1x, which means the BTC drive will only write to that media at those speeds.
As others have mentioned, that particular MID code is probably not in the firmware, so by default for safe-writing reasons, the drive limits the available writing speeds.
Since you're at FW0258, you'll probably want to keep an eye out on future firmware revisions.
