Is There Any Way I Can Record My Xbox 360 Gameplay Using Only The Materials That I Already Have?

I have a digital camera, but no RVA input/output thingies.
I have a webcam, but I doubt that’d do anything.
I have a 120gig harddrive
I have a dvd player, but not recorder (atleast I don’t think, it doesn’t say it is, though).
like 3 ethernet cables.
Uh…that’s about it.
