Using gamma correction, levels or combined brightness & contrast will produce better results than just increasing the brightness.
Also, you may want to increase the saturation a bit, especially if the footage was shot with a 3-CCD camera (if it was shot with a single-CCD camera, increasing the saturation, coupled with the increased brightness, will probably add too much noise).
And of course (something most people learn the hard way ), if you want a consistent image, always use manual exposure. In fact, if you are reasonably experienced (no need to be a pro, a vague idea of what each setting does is enough) setting everything (shutter, aperture, white balance, gain, etc.) to manual is usually a good idea. The only thing I sometimes leave set to auto is the focus, and even that, only when I'm going to be moving the camera or zooming in and out (low- and mid-range cameras usually can't keep the focus distance when you zoom).
Thanks for the info RMN, I'll give that a go. These videos I'm transfering to DVD are my Dad's home video's on Sony 8mm taken as far back as 1986! All are auto-exposure as that's all the camera would allow as far as I know. Definately a single CCD. I'll go and search for a gamma filter for virtualdub.
