Conexant bt878 driver for windows 7

Have you tryed windows update?

Yes i have tried windows update without any luck, i also have tried the old drivers  
( http://btwincap.sourceforge.net ) but they didn't work either.....

Hi in this link there are few cards that use the same chipset :

Thank you for the tip Amnonm , but i have already tried these. Can you show me a way to install those drivers manually.

I get this error when i install that driver from the link....

In the Device Manager, right click on the device and select properties.
Then select the "Details" tab
Use Ctrl+c to copy the device instance ID string.
Then paste it (Ctrl+v) in your reply.

There are additional drivers around the internet.

This driver has been used by a number of people successfully, however I cannot test it as I don't have your model of card.

You haven't told us which make and model of card you are using.  This might help.

Also keep in mind that not all hardware is compatible with windows 7.  You may need to upgrade your capture card to something more mainstream or modern.

Check your card here: http://www.microsoft.com/windows/compatibility/windows-7/en-us/

@ edbedb. Did you mean this?

That board is a Pinnacle PCTV Pro PCI and you can find the drivers here: http://cdn.pinnaclesys.com/SupportFiles/PCTV%20Drivers/ReadmePCTV.htm

Here is a list of drivers that might work.

Personally I would try this one 1st

Extract the download to a location you will be able to find. Try running the setup. If that fails try using the Hardware Wizard to install it manually.
A good place to start to find drivers by the VEN/DEV ID is www.pcidatabase.com. Not always much help though. This case is a good example.
 

Vee, I just google the ven_??????&dev_?????

Here is a guide how to install drivers manually:
http://www.addictivetips.com/windows-tips/how-to-install-hardware-or-device-drivers-manually-in-windows-vista/

if you will have problems post again but i think that this will solve it

I have tried that Amnonm, but it doesn't work.
@edbedb this is the ven/dev : PCI\VEN_109E&DEV_036E
what should i do now?

So where'd that JPEG come from?  Did you try the link I posted? http://cdn.pinnaclesys.com/SupportFiles/PCTV%20Drivers/ReadmePCTV.htm 

i  tried it but not all of them, still working on it

@DavisMcCarn. i have tried all the drivers on the link. What should i do now?
do you have any idea how i can find the mancufer of my device?
Thank you for your post.

On that page, it should be the PCTV Pro PCI.  That one matches the PCI\VEN_109E&DEV_0400 from your picture.

Try giving us the Hardware ID from the details ( i.e. PCI\VEN_109E&DEV_036E&SUBSYS_13EB0070&REV_11 which is my Hauppage board)

And rats, I forgot; are you running Windows 7 x64 or normal 32 bit?

PCI\VEN_109E&DEV_036E&SUBSYS_00000000&REV_11

Here it is.

i'm running on windows 7 ultimate x64

1) If you have more than 4GB of ram, that card will never work as it won't be able to map a memory windows.
2) Your only hope (roll up your sleves) is going to be to go back to that Pinnacle link, download the x64 Beta drivers, unzip them, and then edit the INF file.  In it, change the line for the 110i card to match your PCI\VEN_109E&DEV_036E&SUBSYS_00000000&REV_11 and then try to manually update the driver.
3) You will have a similar problem with the tuner and the sound controller where it may get stickier.  You'll need Universal Extractor to "unzip" the other CAB files so you can edit their INF files to match the other Hardware ID's which won't appear until after the first driver is installed.
If you've upgraded your systemboard and have PCI-Express X1 slots, I might suggest this for $39.00 http://www.discountelectronics.com/index.php?l=product_detail&p=7071 which would solve the 4GB problem, too.

It should be Vista x64 drivers since the architecture is the same
take the vista 64 drivers and install manually without running the setup just direct the path from device manager to the folder where the drivers located

windows 7 ultimate x64??? That would have been good to know at the start. Give this one a go.

edbedb; Sorry, they are only for BT848 and reference PCI\VEN_109E&DEV_0350

Then what is this line for?
%BT848.VideoDeviceDesc%=BT848.Main  , PCI\VEN_109E&DEV_036E

Note this recommendation from "nobus" - it has worked for me every time:

<<try this to identify the devices :

Start-Programs-Accessories-System Tools-System Information.
Click on "components" and highlight "problem devices".
All hardware devices with a driver problem will be listed here.
Make a note of the first line of the PNP Device ID line of the entry. It will show a Vendor number and a Device number (VENxxxxDEVxxxx) both four digits long.
Look up those numbers here:   http://www.pcidatabase.com/index.php

This will tell you the manufacturer and the chip number.  Check the manufacturer's website first or google them>>

Have you tried installing te driver sin the windows xp compatibility mode?

Thanks

I followed youghv's advice and i did what he suggested, this is what i got:

  Multimedia Controller      PCI\VEN_109E&DEV_0878:

0x109E      Brooktree Corporation
0x0878      TV Video Capture: Hauppauge WinTV GO      0x109E      Brooktree Corporation

  Multimedia Video Controller      PCI\VEN_109E&DEV_036E:

0x036E      video capture device      0x109E      Brooktree Corporation

Have you tried manually installing the last driver I provided? What happened?
 

We're back at the rock and a hard place......
Brooktree/Conextant never wrote any x64 drivers for that chip and I was surprised that Pinnacle had.  If you had used Windows 7 32 bit, we could make it work (as long as you stay below 4GB of ram); but, in x64, the only shot is to edit the INF files as I mentioned earlier and, even then, we might have incompatability issues between the Pinnacle drivers on the Hauppage card.
You may be able to force the installation in XP compatibility mode; but, even if you succeed, it is a path for major instability issues as x64 hates 32 bit drivers.

@DavisMcCarn
 Thank you for your replies so far. Now how can i exaclly modify the .inf file?
I want to give it a last try, if it doesn't work then i will leave it.

It worked, can you tell me a tv tuner software to try it out?

Start by trying the Media Center that came with the 7 Ultimate.
