I have noticed, at least in Vista when ever I am doing ripping, muxing or burning my system slows down to a halt. I have 4GB of ram but when I am doing those things, I am only using 1.6GB at most and it slows down like I am using 3.9GB. I was looking at the Task Manager during this, and it says under Physical Memory that I have 2813? Is that correct, does that not mean I have just under 3GB of RAM? Anyone got any ideas to why? For either question..
