Aren't you afraid to spoil your system with all kinds of rootkits by using
Sony stuff ?

The Hardware Manufacturer's are responsible for the drivers for their
products. You'll have to check the Sony website or contact their tech
support to find out if they are supporting that model in Vista.

What are they supposed to do, buy a new video camera. I don't think so! It
should just work, the same problem I'm having, nothing friggin' works with
Vista. I'ts a crock.

I really don't understand why these folks don't [or can't] realize
this, Andre. Why would one expect to be able to get a driver from
anyone but the manufacturer of the device? If the manufacturer
doesn't [or won't] provide a Vista driver for their own devices, those
owners are just out-of-luck, and need to face reality sooner rather
than later. Or they need to use an OS for which the manufacturer DOES
provide drivers. Or they need to start a "movement", and demand
drivers from the manufacturer.

Microsoft, in league with many device manufacturers, provides many and
diverse device drivers with each iteratio of its OSes. Expecting them
to provide EVERY device driver for EVERY device a user owns [or could
conceivably own] is completely unreasonable, considering how many
OEMs there are out there. To even consider such an idea is a waste of
the user's [and our] time and intellect.

But OTOH if you buy a car from Ford you don't expect to have to have to
evaluate every nut, bolt, seatbelt, oil and air filter to make sure the
thing works as a car.

People's expectations of compatibility are partly due to Microsoft's
past efforts as maintaining it. XP has drivers for vast numbers of
things, and they work, it is what people are used to. Not every driver
is familiar with the technical aspects and pitfalls of buying a new car,
why expect them to be with a new operating system...

I do understand your logic. However, it is only useful to create
emotional responses in your readers.

Your resoning IS a little specious, and for these reasons.
1) Microsoft is not Ford.
2) An OS is not a piece of machinery such as an automobile(except
maybe metaphorically).
3) While Microsoft HAS worked hard to make their OSes available to the
widest possible number of computer owners, they do NOT have the legal
rights to write drivers for any-and-all hardware device, since they do
not manufacture them.
4) Microsoft always works closely with the OEMs who want their devices
to be included in the Windows Hardware Compatibility List to write
drivers, if the OEM has no in-house device driver writers..
5) If an OEM refuses to give Microsoft the necessary information which
will enable them to write a device driver, what can Microsoft do?
Absolutely NOTHING, but buy the device manufacturer. While Microsoft
has a plethora of cash, they simply don't have enough to buy every
device manufacturer, not would those manufacturers necessarily WANT
their companies to be sold to ANYONE.
6) Microsoft is NOT required to include compatiblilty for any and all
devices by ANYTHING but the Market, and their own bottom-line. Anyone
can see that they are not worried about their bottom-line, so unless
the users and manufacturers can make a good enough case for their
particular devices, they simply won't.

I can't say any more, since there is nothing more to say about this.
Just accept it, and bite the bullet if your particular device has no
driver from Microsoft, and buy a device which does have a compatible
driver, either from Microsoft, in union with the manufacturer, or from
the manufacturer itself.

BTW, in many cases, especially with Vista, devices fail to work for a
simple reason: The manufacturer has chosen not to make their device
compatible with Vista, since it would cost too much money, so they
make one which is, and usually charge more for it to make up the cost
of making it compatible with Vista.

This has happened with each iteration of Windows, and will continue to
happen each time there is a newer iteration of Windows. It's all
about the money, my friend.

Let's face it: ALL computer and software manufacturers are in it for
the money. This is never going to change. If they can't make money
with their products...Well, you know what happens when a manufacturer
stops making money. We all do.

Spoke with someone from Sony, most video cameras are equipped with a usb
streaming method or cable. Windows Vista does not recognize this connection.

Spoke with someone from Sony, most video cameras are equipped with a usb
streaming method or cable. Windows Vista does not recognize this connection.
You have to purchase a dv cable with a IEE plug so Vista will work with
these cameras. I have the Sony dcr-trv250

What you are referring to is called a "Firewire cable"...
It uses an IEEE 1394 connection/cable [the connector looks much like
an USB connector, except one side of the connector is slightly
rounded. This connector will not fit into an USB female connector]

In fact, many video cameras use the Firewire standard, rather than the
USB standard. Firewire cables are extremely cheap, and the transfer
speed of Firewire400 cables is 480MBPS, rather than 400MBPS, as it is
for USB 2.0 cables.

Thanks for the real important info. I have close to 100 videos of trips
through Mexico and family videos that I have wanted to put on DVDs for a few
years now and been unable to transfer them. All we could do is watch them on
the tiny camera screen or plug the camera into a TV. I started out with XP
X64 bit OS and then installed Vista Ultimate X64 bit. Sometimes I have to
download a patch or an updated version of a driver but every single program,
game, hardware, or whatever has always worked with both systems>>>>>EXCEPT
SONY STUFF. All other companies make a driver or patch to make there
products usable except Sony. With your advise I have spoted a DV output port
on the camera and my PC has firewire so I can't wait to see if it works. I
was going to go out and buy an old PC just to get the pictures out and on a
DVD. I have the DCR-TRV250 Sony Digital 8 Hanycam and it's picture quality is
great. Since it did not work with any PCs except for the old ones I never
owned, I had to buy a new Memory chip all digital camera and really easy to
load the videos/pics into the PC, printer, etc. Thanks for the info. and how
did you get to talk to someone from Sony? Thanks again. RetroDoctor out

My Sony camera infact has both usb and ieee or firewire connections. The
problem is according to Sony the Vista operating system does not recognise or
allow the usb connection and the new computer I got so that I could get video
off my camera (I had a Vista 64 system and was told it only worked with 32 so
I downgraded) does not have a firewire/ieee port. I still cant do anything
with all this video! I haven't found any way of useing another driver...

Thank you for that link. My problem remains however since the new computer of
course doesnt have a firewire/IEEE port. Nor does it have a slot for the
adapter card I had for an older camera and laptop to make a firewire port...
This camera was supposed to work with usb so I wasn't paying as close
attention to the firewire port.

I also have A DCR-TRV250 Digital8 handycam. can I use a Firewire?

Seriously. You read all that and responded to it with that query?

The posting was started in July 2007. (It is the end of March, 2010.)
http://groups.google.com/group/micr...a.general/browse_frm/thread/311fd66c6a544873/

The support for your product (doesn't matter how old it is) is best gotten
from the manufacturer. If they refuse support/don't have any available -
that should tell you something about the product in question (it's
out-dated, etc.)

Yor best bet is reading your user manual (and ignoring the OS information,
as it obviously was not made to last past Windows Vista in terms of product
life anyway.)

Lost your manual (that should tell you something right there, hah) - no
problem...
