I've seen quite a few instances of this happening with HDV tapes/ cameras of all makes, and have been puzzling just what gives to cause it.

My best guess (and believe me, I claim no specialist knowledge in this field) is that the pictures you are seeing on FF or Rew are in fact the key frames, which can be read as the camera only needs to detect the block header data and nothing else to read it.

I surmise that in order to decode the rest of the block it requires a sequencing/ timeing signal that is either not present, corrupted or cannot be detected for whatever reason.

Assuming the camera is actually functioning correctly (or thinks it is) the only common denominator here is the tape and it's path through the mechanism.

Given the minute amount (microns?) this path could be out, the only way I can see to get this data is to plonk the camera and tapes in front of a Canon tech who really knows his onions and has the necessary equipment to re - align the tape heads/ path enough to get a readable signal.

Of course, this could be a complete load of hogwash and/ or the said Techie does not exist (even if he/ she did exist can't see him/ her being within a bulls roar of Regina!).

Sorry if this has been of absolutely no help whatsoever, but if you're getting desperate, it calls for desperate measures.

PS: It would be interesting to know if the HV20 that wrote those tapes can actually read tapes written in another camera/ drive. I'm not sure quite what that piece of information adds to the story, but it would be usefull.
