Or perhaps we understand full well but are afraid that
you (and everyone else who buys one of those camcorders)
is just stuck with it. If you can't fight City Hall, fighting a
humongous international corp is even more daunting.

I would feel just as angry, disgusted, and ripped-off as you
do. Alas I don't know that there is anything practical we can
do about except maybe a class-action against Sony. But you
would need some kind of legal spec to hang your hat on. But
Sony seems to have created themselves a giant loophole by
not publishing any audio performance specs.

The description of FS digital noise is a common symptom
of an audio bitstream that has lost synchronization. It makes
me think that the codec is not as robust as it should be to
try to take that much video and audio data and squeze it
into the 25MB/s bandwidth of DV.
