It maybe a little bit late to answer this question, but I just noticed... anyway, my IVision LabVIEW toolkit can do just what you asked, capturing video from WDM supporting capturing devices such as USB camera, IEEE1394/firewire camera or DV camcorder. To get an evaluation version, you can download using the below link:
I tried the evaluation version of IVISION. My video card is all-in-wonder, and the toolkit worked well. I could catpure video signals by using demo vi included in IVISION kit. But one problem is that I got 'squeezed' images when I did snap images. I think it's because some VIs included in the IVISION toolkit (IVISION_ImageToArray.vi, maybe) have a fixed-size ROI (320x480, in my case). The VIs blocked, so I couldn't find a way to change the ROI settings. Have anyone suceeded capturing unsqueezed images?
