There is a MK1 and MK2 version of the STB controller. Or at least, of the software that you use to program it. The launch document of the Bv8 mentions this. BV8 has the later one and there it seems to work.
If nobody here knows, you can contact Beocare at bangandolufsen.com , they can find out from product management. At least for me they did.
