If all software has the same problem, then I suppose the fault is with the firewire cable/card or your camera.
If the problem is the cable or your camera then even buying a mac won't help you, maybe you could try to capture on a different computer, just to check your cameras/cable isn't causing it.
It would suck to get a decent editing system and then still not be able to capture.
