Well, you still haven't said what errors you get regarding nullPVR (drkPVR). I should work with your GeForce 4 (it even works with my GeForce 2 MX) although it would be slower than Chankast PVR.
Having an error while initing a plugin means that there is a problem on that department. Are you sure that you have sound acceleration enabled and sound actually works for you?
Last but not least, a screenshot of the GFX problem(s) you have would be helpful.
