Hello, I have a kingston 8GB sd card. I use it in my Sanyo camcorder. I used that memory card in my Nikon camera and recorded some videos. When i was done, I saw all the videos and then removed it and inserted it back in my Sanyo camcorder. I was not able to see any of the recorded video in that camcorder then i inserted it back in my Nikon cam and i was able to see all the videos. I thought that when i would connect it to my PC, i would able to see all the videos and then kept my camera. After 1 ore 2 days i removed the memory card and then inserted it in my card reader and connected it to my PC. I only found the old pics of Sanyo camcorder. I then inserted it back in my nikon camera but videos were not there.
