Howdy aaz!
In the two Hitachi models that you refer to above, there is
no advantage in having a higher pixel CCD when it comes to
the video mode.
It only gives you an advantage with still images (JPEG) with
1280x960 resolution for the DZMV380A versus 640x480 for the
DZMV350A.
It appears that the higher resolution CCD is there "just" so
you can have a megapixel JPEG image on the DZMV380A.
Hitachi's own web page on the DZMV380A seems to infer as much.
http://www.hitachi.com/tv/browse/camcorders/dvd/dzmv380a.shtml
"While providing excellent video quality, the MegaPixel CCD image
sensor with 1.0 million pixels [provides] for high-resolution still
photos."
Is the approximately $150 price differential between the two models
( according to the CNET Shopper website at http://www.shopper.com )
a good price for the difference in still image resolution? Possibly
not if video is going to be your primary focus. But when you are
dropping $800 for a DVD camcorder, what's another $150 for twice the
resolution when it comes to still images?
If you need any clarification, feel free to ask.

So is there any relationship between 'CCD's pixels' and 'video
resolution' in DVD camcorders?

The two models I quoted in my question offer 720,000 and 680,000
pixels.
Your first response:
"In the two Hitachi models that you refer to above, there is no
advantage in having a higher pixel CCD when it comes to the video
mode."
Your latest response:
"1.1 megapixel CCD camcorder uses 720,000 pixels for video,
680,000 pixel CCD uses 340,000 pixels for video"
The two responses conflict. Kindly clarify. For $2, I am asking too
much.
I will make up to you, if I get an adequate response.

Howdy aaz!
First, please note that the Comment below was by eiffel-ga,
and not by myself (denco-ga). Apologies for any confusion.
Secondly, the Hitachi web page that eiffel-ga references is
about the DZ-MV270E/DZ-MV238E versus the DZ-MV208E and has
nothing to do with the DZMV350A or the DZMV380A. You have
read the Hitachi pages you referenced in your original
question quite rightly in that the DVD video mode is indeed
704x480 for both of the referenced models.
You ask "So is there any relationship between 'CCD's pixels'
and 'video resolution' in DVD camcorders?" and the answer
still appears to be no, there does not appear to be any
relationship, or advantage to having a higher resolution
CCD, at least when it comes to these two models of Hitachi
DVD camcorders in video mode, and the Hitachi site does not
state anything otherwise.
That said, there might exist a (for example) 1 megapixel DVD
camcorder that does use the higher resolution of the CCD in
video mode, but the DZMV380A is not one of them.
Looking Forward, denco-ga

Thanks. I indeed did not notice that comment was by another
researcher.
But the answer does not make sense to me. CCD has certain number of
pixels. Whether video mode or still mode, the pixels have to come from
CCD. There should be a relationship between CCD's pixels and the video
output. And if there is, why would only Hitachi's old models follow
that relationship, not new ones?

Another Hitachi site says that the two models (DZ-MV350 and DZ-MV380)
do offer different pixels in moving mode: DZ-MV350 offers 410 K;
DZ-MV380 offers 570 K.
To get the above info, go to:
http://www.hitachiconsumer.com.sg/products/sing/sing.htm
Click on 'Movie Camera' in the left column
Click on 'DVD Camera' icon
Pl note, there are PAL cameras and NTSC cameras. The above site is for
Singapore and offers PAL camera details. In Japan and the US, the
cameras are NTSC cameras. The specifications may be different but the
SG site proves that the higher the pixels on CCD, higher the pixels in
movie mode. If it holds true for PAL cameras, it would be true for
NTSC cameras.

Howdy aaz!
I called Hitachi (at 1-800-448-2244) and spoke to one of
their technical support people, and they stated that the
numbers of pixels used in video mode on these models was
the same, 704x480, and that the extra pixels offered by
the DZMV380A are only used in still mode.
I agree that the PAL models have different specifications
than the NTSC models, but it is not unusual for companies
to have different specifications for different formats or
markets.
I truly am not trying to be argumentative, but just because
the models in the past have been of one type of specification,
or that the PAL version has a one set of specifications, doesn't
mean that there will be any type of sense, or correlation to be
made of or to their current NTSC model specifications.
If I had to make an educated guess, it would be that Hitachi
was trying to make a product line that had some differences,
but didn't want to put the time and engineering into making
the differences in video mode, at least not for the US market.
There might have been technical and/or engineering issues, but
the only difference between the two referenced models, according
to Hitachi's website and their technical support staff, is the
resolution in the still images they take.
If I could've found anything to support something different, I
would be more than happy to share it with you, but I haven't.
Looking Forward, denco-ga
