same problem with new dsc-p32.. had camera about 45 days and then all the sudden memory stock error... the memory stick works fine in my other 2 sony cams but no other sticks work in this camera now.. i called sony she said rest the camera but does not work either. She said take it to nearest auth sony center which 380 miles away in California... I am also past my 30 day return so now im screwed.. sony will not even acknowledge this problem on there web site either.. i told her to make sure she notes that in her report that they should at least acknowldge this as a know problem or defect.. this stinks!
