You'll have to find out whether your capture card is "Video For Windows" compatible, because many capture cards have one program that they're designed to work with, and won't work in third party software at all. I've got a capture card like that, it doesn't get recognised by third party programs. If it's not Video For Windows compatible, it'd be a case of searching for that feature in the bundled software, if it's not there, it won't be possible.
