I've had that happen on my office computer while using MS
Media Player. Mine was an OS configuration issue that had
nothing to do with the file itself.

Phenomenon is the singular version of the word.

But you didn't say what (if anything?) DID get recorded?
Was it silence? Was it the on-camera mic? Better analysis
of the symptoms will help pinpoint the problem. Did the
camcorder slip into 4-channel mode or something?

I would doubt it. The audio and video information are
interleaved frame by frame and disruption of the bitstream
sufficient to mute the audio would almost certainly blank
the video (or at least cause visible "pixelization" ).

I'd be suffering from hysterical deafness (and blindness) if I had
to do 40 weddings in a season! Unless the picture is also suffering
from concurrent degradation or blanking, I would NOT use the
abrasive head cleaner as a solution to this problem.

If you are truly hearing the wireless audio in the headphones
while recording, but not when playing back, I'd first suspect a
problem (open circuit, etc.) inside the camcorder.

Thanks for the opinions. Sounds very on target. Humbly, Ed

Didn't someone else report changing levels on a PD150 a few months back?
