Windows no longer recognizes my video card input.

[Why Windows? Why?]

I have a GeForce Ti4200. I have been using Win Producer to
transfer some old movies to VCD. Now, however, windows
does not recognize the video input on my video card nor the
audio input on my Soundblast Audigy.

Is there something fairly obvious I am missing? Somehow I
must have turned it off??? Windows Movie maker also does
not recognize my video card nor my audio card.

All my other applications work fine.

Please help.

First thing I would try is re-downloading and installing the WDM Capture
drivers from the nVidia website at www.nvidia.com
