random no audio, dropped frames

OK. I taped a live with 3 cameras, 1 JVC HD100 and 2 JVC HD 250s I rented. They all had brand new JVC ProHD tapes in them.

I transferred the tape to my desktop using Adobe PPro CS3. It was one of the tapes that was in one of the 250, and being played in the 250. On playback, the tape looks fine.

But there is a large chunk with no audio attached to the video. Audio on the tape, but only video was captured. And that occurred inconsistently - there are chunks where the audio is there, but these usually have a lot of dropped frames.

Now I'm transferring the tape from the JVC HD 100, using the JVC HD 100. I'm getting the same thing.

The 3rd camera was attached to a laptop, which captured the footage with no problem.

Any ideas what happened to new tapes in two different cameras? Any way to salvage the tapes?

If anyone is still interested, I found a solution -

I used HDLink, which is part of the Prospect HD software from Cineform. HDLink has it's own interface to the camera, and when I used that, it worked fine, absolutely fine.

The rental place suggested using the batteries to power the camera, as the voltage at the venue might not be consistent. But I found one of the batteries they supplied started saying 'low voltage' after about 20 minutes. They were Anton Bauers who were supposed to last hours, and they were fully charged.

So I went to AC power, rather than have batteries die in the middle of a live event. Maybe the power did fluctuate?
