Naively, I transferred a small 2mb mpeg file (a small trailer) to my nokia 3650 as an experiment. There is nothing wrong with the file itself. I expected the 3650 pc suite software to convert it to a suitable format but it didn't do so. When i tried opening the file it said it "unknown clip format". When i try deleting it it said "UNABLE TO DELETE". I even tried deleting it through the PC suite software but it said that the file is either in use or is read-only. I'm at a loss. Could it be that the memory card is faulty?
