How to change IRQ for capture card in W2K

[EmaK]

I go in the device setting but it wont let me change anything there.

change the PCI slot OR change in bios setting if your bios supported.

I went throught this same problem. The short answer is YOU CAN'T. Windows 2k overides ANY
BIOS or card settings. If you go out and search MS knowledge base you can find several notes about this. There IS a way to do it, but it involves really messing with Win2k, and they REALLY warn you not to do it. You have to rip out a central part of 2k and replace it with another section of code, but they warn you, you can't go back and forth, it takes an OS re-load.
Even though Win2k has practically ALL my cards sharing IRQs, I'm still capturing just fine, and only drop one frame per 3000. Which I thought might be an IRQ sharing issue, but since then, I've follwed several threads suggesting it's more liekly an issue of purposful frame dropping to keep the audio in sync. My VCDs look fine, and I'm not going to mess it up worse.

Hi,

Thanks for the info. I am dopping frames like 50%+ so gonna check to see if it's other things.

Thanks again

EmaK, what video capture card are you using? If it's a Nvidia GeForce (specifically ASUS) I was part of a long running thread about how broken ASUS video capture drivers are under win 2k. I couldn't capture for squat. Found a bootleg Nvidia WDM driver, fixed it right up!
Or could it be your hard drives? how fast, at least 7200RPM and ATA100? have DMA set right for the drives? Happy to help if I can!
