My capture card seems fine

In what way? If its not producing video output then how can you tell?

When I go in to capture mode to work, all I get is a blank blue screen, I cannot see any video.

My experience with older capture cards suggests to me that you may have a driver problem. What is the source of your drivers?

If you have any setup applications that come with the driver, have a look and ensure that you have everything set correctly and that it is set to the correct input if your card has both composite and s-video. Depending on your card, going to VirtualDub in capture mode and clicking 'Video>Capture filter' can give you some options.

I have used both 32-bit and 64-bit versions of VirtualDub in the past and for capturing I had no problems with either, provided you have set the correct resolution and frame rate within the settings. For actually using VirtualDub for processing video though, I stuck with the 32-bit version because its just so much easier for compatibility with AviSynth and plugins.
