Unable to capture Video from DV cam. using firewir

[ostech]

Good day all forum friends.
I have a problem capturing video form my JVC DV camcorder. I have used the default windows capture program, JVC' own capture program and Video Studio 10+. Here are my computer details: Windows XP pro SP2. Celeron 3.06g processor. 200 & 80 bg hard drives. Firewire card.
The problem: None of the programs listed above allow me a preview and return an error. Yet on another computer, with the same camera and firewire card, I get no errors and a preview and capture.
Why not use that computer? it has a small haed drive, 1.7g processor and will be unsuitaple for extensive work on video files. I have uded Device manager - "no conflicts", "device is working properly" I have diabled firewall, removed and reinsgtalled video programs, cleaned registry. Still unable to capture.  "failed to bulid preview graph in VS10" "unexpected error" in Windows capture program. Even changed firewire card - same problems. I am at a loss can someone help me please.

What are the differences in the video capabilities of the 2 machines ? ?

[ostech]

Thanks for your quick response, Not so sure about your interpretation of video capacities. Only to say that the computer it works on has 512mb ram 1.7g celeron processor, 80 gb Hard drive, no video or games card. The machine it dos'nt work on has 1GB ram, no other card but the firewire card.

I believe patio means the video card.
But do correct me if I'm wrong.
You say it has no video card -that's impossible.
It may have no dedicated card but it has to have an on-board card, or you'd get no video output at all.
So patio's question, as I interpret it, is - what video card does each machine have?

Thanks Calum.
I will check the mother board for the video card and write back to you.  I guess what I meant to say is that I have no graphcs card.  While I'm on, I just need to say that the motherboard I am using is a Chaintech MPM800-3. It has been very difficult to find out from them if the problems Im having, existed before. Incidentally the lesses motherboard  is from Biostar.
Thanks for your help.

Your Chaintech motherboard has integrated S3 Graphics UniChrome Pro.
If you can find out your other motherboard model, that would be useful.
Hopefully the info helps someone to help you.

Calum,  Thanks again for your input.  The other motherboard is Biostar U8668-D Ver 5.0.  I just looked at the users guide of the Chaintech motherboard and seen  a heading CN16/26A(IEEE1394 connector).
I suppose I should try to locate this connector on the motherboard and see if it works. I presume I shall have to find an adaptor cable of some sort. Your thoughts please.

The Biostar has "S3 ProSavage 8 up to 32MB shared video memory" graphics.
Hopefully this helps someone out as well.
The IEEE1394 connector is Firewire . . . should be easily accessible.
If you can find it, try plugging the camcorder into that and see if it works.

And make sure bluetooth is enabled in the BIOS and has the drivers installed from the MBoard driver CD that came with the machine...

[Calum]

Bluetooth?
Why?
Am I missing something?
Or is it a joke/mistake?
:-?

[patio]

oooops   firewire.

[Calum]

Hee hee.
Not often you make a mistake patio.
I also never knew Firewire was in the BIOS.
Although I suppose it does make sense.
You learn something new every day, they say.

[patio]

It actually might not be but it's worth a looksee...

Thank you gentlemen for your input. I will try all the recommended options and post the results.
