hmmm... 4 actually seems like a lot to me, but i run that last to pick up on nasties the others miss, so maybe not. if you want, i'll put together a pdf file sometime in the next few days with instructions, graphics, etc. for everything i use and how to use them. it won't contain all the tweaks i usually do during install because all the machines i have already have them installed, but it should get you in the right direction for some pretty tough protection. MIGHT (no promises) just get you where you need to be with your sound, might not... but good to have anyway.
it's all free and it's about time i clean up the kids machines anyway, so it's just a little extra effort on my part.
