lawrence,
How low is the "low lighting" you mention? There is no one setting that's going to magically make a really low light situation look like a nicely exposed and well lit shot. In video as in photography, it's all about the light. There are some helpfull settings for lower light situations, and I'm sure they are still archived on dvinf. The lower the light and the more gain you use, the less clean and crisp the image will be.
