Right so I capped this video from vhs, and it looks to be interlaced

I don't think this is the macrovision problem so I figure I'd try to cap it and run it in vdub and see what happens, well I checked the file I originally capped and it looks exactly like the screenshot, I load it in vdub , vid and aud to full and add the deinterlace filter and selected the first one the blend best one. Then I saved the avi and the process ran, after it was finished I played the output file in WMP and there was only sound and no video.
