I was just wondering why users all over the net are going from 3.71 M33 to 3.71 M33-1 e.t.c. I know they are patch firmware from what I understand, adding a patch to the 3.71 M33. But why?. I have had my 3.71 M33 firmware for a while now & everything works great, so I don't see the need to upgrade. Anyone?
