Essensially the same hardware. See the two links. The 111D is much more common throughout the globe, the 111 was mostly japan, 111b is a little more adaptable than than 111, more FW options.
DVDINFO is misleading they both do auto bittsetting of DL+R right out of the box. It just can't be changed, its "Auto" to dvd-rom, which almost if not all dl+R are, auto-set to dvd-rom. But they don't all write as well as the pioneer. DvD-info won't say it but after you burn you can use dvd-info to check the media properties after you burn your first dl+r with it and it will say dvd-rom.
Hacked firmwares can be little risky this partical series of drives. If your just trying burn DL+R back-ups of xbox360 games just stick with official firmware's if you updgrade to avoid flashing issues. And I would just burn with the stock FW first.
If you want the best hacked firmware that has all bells and wistles, buffalo, makes the best hacked fw for these drives. But if you read below, their are some issues flashing to some of the various hacked firmware's with these drives.
