Something to try?? (v3400 model users...)
I have the following setup:
ASUS P2B (1.02, BIOS 1014 BETA 001)
ASUS V3400TNT/16/TV (SDRAM model, BIOS 2.04.17)
Windows XP Professional
German ASUS Drivers v29.80
I have tried installing ASUS LIVE 4.6, 4.6b2, and 4.6b5 with no luck. I have tried using WDM drivers 1.08 (nVidia), 1.08 (ASUS PAL patch), and 1.11 with no luck. Originally ASUS LIVE gave me the "no I2C" support error, but as Netfinder posted earlier, there is an "i2cinst.exe" file included in the ASUS LIVE package that fixes that problem.
As others have encountered, my "nVidia WDM Capture Driver" always errors with Code 10 ("Device cannot start"

.
I sent an email to ASUS, and actually got a reply back the next day (today). They indicated, and here is the catch...
ASUS LIVE does not yet support Windows XP! At least no released version.
ASUS suggested I try the ASUS Digital VCR for Windows XP. I have submitted a followup clarification request because the link to their DVR software does not indicate that it supports the V3400 card. I will post again when/if they reply, clarifying whether or not v3400 cards are supported with the DVR software.
I have not yet been home to try the DVR software, but I wanted to go ahead and post this information hoping that it may help some other frustrated customers. Below is a snippit of ASUS's email with the steps to follow.
Hope it helps!

Dear Customer,
Thanks for choosing ASUSTeK.
We have not released ASUS Live Utility software for Windows XP OS. But we have new capture software, which is called ASUS Digital VCR software version 2.2 for our VGA card. Please download it from our website as following URL:
ASUS Digital VCR 2.2 needs the nVidia WDM capture driver installed. It is available from:
Installation Process:
1. Windows XP OS installation
2. Install Motherboard AGP driver according to the motherboard chipset.
3. Install ASUS Windows XP driver.
4. Install ASUS Digital VCR software 2.2.
5. Due to those drivers are not certificated by Windows XP, please install them anyway. After reboot, it will auto detect the new hardware and install all of WDM driver and capture driver.
6. Please open Windows Device Manager, if you can find "nvidia capture device", "nvidia audio/video crossbar", etc in "Sound, Video and Game Controller" list and without any Unknown Device, then you can run our ASUS DVCR program for testing.
