Hello this is about my sony video camera. This past week I recorded something and when I go to play it back all I see is a blue screen and after fast forwarding for a while(about an hour into the taping) I see the video i recorded. I rewinded the whole video today and taped something in my home n played it back. The recording I did today shows up then the blue screen from what I previously taped n then the little bit is showing about an hour into the tape. How do I get the original taping without seeing a blue screen?
