question about ATI WDM drivers

[dumwaldo]

i just came across this...

Most likely because you are using WDM drivers with the ATI card and VDub needs the older VFW drivers. There is a "wrapper" available that converts from one to the other, but I've never gotten it to work with my ATI card, so I'm stuck capturing with the MMC software.

this is not the first time i have seen this advice offered to ATI owners and it draws a question in my mind that perhaps someone can help with.

i use a Visiontak Xtasy Everything card with VirtualDub 1.4.5 to cap. VirtualDub uses nVidia WDM Video Capture (universal) as the device in the source box under the video pull down. i was under the impression that means it is using the WDM driver for capturing.

so my question is this, am i wrong thinking i am using a WDM driver and if i am not wrong why does the ATI WDM driver not work?

I have read that the only software that will work with ATI WDM drivers is ATI's MMC. I have managed to get theWDM->VFW wrapper to work with the 4.12.6292 driver which is trivial since the driver support VFW. That was the only driver I had success. I 'assume' the folks that have the ATI Radeons were capturing using the wapper.
