Jumpy Jittery Video Capture on one computer

[Guest]

I have two identical machines. Both with sufficient disk space.
One does analog video capture with no problem the other has appears to
'remember' the first image it sees and then bounces back and forth between
that image and the video it is capturing.

I also have a VCR program that came with the machine. It works fine
capturing analog video. I only have the problem when using windows
moviemaker.

Digital capture works OK.

(My inclination was to uninstall WMM2 and re-install it but there seems to
be no way to uninstall.)

The driver being used in "nVidia WDM Video Capture (universal)" on both the
working and non-working machine.

Hello,

Drivers for NVidia are best obtained from the manufacturer of the
graphics card itself.....DO NOT use the driver supplied by Microsoft, it is
generic and will not work well with the higher end NVidia cards. Instead go
to the site of your cards manufacturer and get "their" latest driver. You
should do this even if the Microsoft driver is more recent.

The reason for this is that manufacturers tend to tweak the NVidia
settings to achieve their own performance requirements thereby invalidating
the generic driver, which conforms to the basic definitions for your version
of card.

John,

First thank you for your information.

I don't think it is a driver issue as:

1) WMM2 works on the other machine - which has the same driver.
2) The VCR program (on the problem machine), which uses the same driver
works fine.

I guess it could not hurt to install the nVidea web site. I won't be able
to try it till next week. I'll post the results then.

Hi,

Just one comment at the moment...

I guess it could not hurt to install the nVidea web site. I won't be able
to try it till next week. I'll post the results then.

No not the NVidia web site, that also has generic drivers....they
conform to the base standard. You should go to the website of the company
that manufactured your graphics card...My Nvidia card is Gainward for
example. The Gainward diver has a lower release number than the generic
one...but it has tweaks in it that enable a much faster card...if I were to
use those from NVidia the card behaves terrible.

John,

I'm not sure what my hardware card is.

I looked in...
My Computer
-> Properties
-> Hardware
-> Device Manager
-> Display Adapter
-> NVIDIA GeForce4 Ti 4200 with AGP8X

Thus I guess I would still get the driver from nVidia, but would I look for
a specific driver not the 'universal' one?

Hello,

Hmm, problem.....the manufacturer of the card is often printed somewhere
on the card itself. If you do not have a card because its integral to the
motherboard then you would have to go to the manufacturer of the motherboard
itself and armed with your motherboard model number search for the graphics
update...it may be a separate entity or it may be included with the
motherboard drivers.

Also, be certain of what it is you are downloading. Installation of a
firmware update is not the same as a driver update and has potential to ruin
your system making it permanently unusable. Having said that I only once had
a problem with a firmware update and was able to recover by doing a BIOS
reset...I was lucky though.

About NVidia....Most people seem to believe that they have described
their graphics card fully when they say I have an NVidia this or that...in
fact all that they have said is that the chipset on their so far
unidentified graphics card is NVidia. A description of my NVidia Gainward
card also includes the fact that the bus speed of the daughter card runs at
some number of GHz (cant remember) and that the CPU on the daughter card
runs at some other GHz and that the speed of each can be varied by the user.
I mention that because you may not be aware that just as it is with a
computer...the bus speed and cpu speed are everything.

I just rebooted the NVidia system in the hope it would give an
indication, it does not, however the control utility does say the
manufacturer etc.

Hope that helps a little
