Failure to open device on capture

Machine is a Shuttle AK31 version 2 Main Board VIA Kt266 chipset, with Visiontek Xtasy Everything Vid card AGP, 512 MB Ram, 2) 40 gig 7200 rpm drives.
Win 98 SE, All works fine, no yellow exclamations in System Properties.

First I have other capture software that works fine:
Virtualdub, AMcap, Avi_io, But with Video Factory (Vidcap25.exe) I get the following error message:
"The device "NVidia WDM Video Capture (Universal)" Could not be opened"

I have removed MGI VideoWave5, I've installed DIrectX9
And basically tried whatever I can think of, Any ideas on how to get this to work?

Have you tried reinstalling your drivers, or checking to see if there are new drivers (which I know is hard to do since Visiontek is belly up). You might want to try generic Nvidia drivers from Nvidia.com

Having said that, I wouldn't really even try to make this work. Even when working, Vidcap is really worthless for analog capture. Basically, it has the same functionality as AMcap. This is because Vidcap is really geared towards DV capture.

Instead, I would focus on getting a really good DirectShow capture application like VirtualVCR (http://www.digtv.ws) or iuVCR (http://www.iulabs.com). Note: VirtualVCR is freeware, iuVCR is shareware.

A word about VirtualDub (and AVI_IO). VirtualDub is a really good application. However, it's capture portion is built around the now obsolete VFW API. All new capture cards, including your Nvidia card, use the new DirectShow API. Therefore, VirtualDub is accessing your capture device through a wrapper. This slows down captures and introduces bugs. Continue to use VirtualDub for its other parts, but don't use its capture portion.
