I seemed to have lost the change to the DD1.1 PVR value. I originally coded it this way while I was waiting to find out what it was. DD1.1 is 0x11A52040. I don't know a value for the future versions, so that will have to be filled in later. Actually, I should probably use 0x11A52000, since that's what's defined in reg.h.
