With that sort of computer power, your rendering time (which is what I assume you are really talking about) sounds about right, or at least in the ball park. Less well resourced computers can take up to 4 or 5 times real time to render from DV to mpeg-2. In other words, to render one hour of video might take 4 or 5 hours to render.
If you click on my System button, you will see my computer specifications. With that, which is only middle of the road or less these days, it takes me between 1.25 to 1.5 times real time to render, depending on the complexity of the editing I have done to the project.
The only real of speeding up the process is to improve the computing capacity of your computer, or buy a new one!
Whoever said video editing was supposed to be quick???
