I have everything including the camera updated to the latest software. I have also formatted the new card in the camera per instructions. My supplied 4gb card works great, but when I installed my new larger card the video is "jumpy". Not smooth at all. I switch back to the smaller card and it works just fine as it is supposed to. I reformatted and still having the problem. Could my new card be faulty? Anyone else had this problem or have any thoughts? Thanks in advance!
