Ok, my general answer at this point would be no.
You may be able to get a component to vga adapter for cheap, but as for DVI... not going to happen. Very expensive - DVI is digital, there'd be a lot of conversion involved.
And then I read that you have a laptop. I find it very curious that you have a DVI IN port on your laptop, but never mind.
The best option I can offer you is something like
this - it takes Component in and outputs Co-ax, I'm not sure how well it'd work with your capture card (if at all) in terms of Picture Quality and Lag.
