Hope someone can help. I have just bought a JVC GR -D93 camcorder and am trying to retrieve some old footage from some DV tapes. The footage is seen for a moment and then all i get is the blue screen.

The footage was taken on my old camera also a JVC which got damaged and started to chew up my tapes. How fragile are these DV tapes? Is it likely that a little tampering could have wiped the whole tape or is it something else?

Would appreciate some help. Many Thanks
