I had a 1GB MMC card working fine. I thought that since I had the gregale firmware installed, a 2GB card would work automatically. But something is not right with my 770 since I started using the 2GB card. When I check the space left on the card from within the 770, it says the card is nearly full at only ~990MB. The 770 also seems to slow down and/or lock up often now. I made a point of formatting the card in the 770 to it's full capacity before writing to it.

What did I miss?
