I had a 512 MB MMC card (from TakeMS) that did not work, it was just not recognized using OS2005. It did work in a card reader at my PC, but not in the 770. So I bougth another brand, and that one was fine.
Since I recently upgraded to OS2006, I just tried the TakeMS once again, and: it works. Without any problem.
