I'm also running ZoneMinder, but the encoding is killing me. I need to find a different codec to use to cut down on resources. Right now on 4 cores, I'm running 40-50% constantly, adn that is only with 4 cameras, and they are going in and out and freezing up. I know it's not the cameras because I'm looking at them through IE (only way to see them in a browser) through the DVR and they are perfectly fine. So it's definitely a codec issue. But, just now learning about about this software so I have a ways to go.
