another vignetting question at DVinfo.net

It seems to be a low light issue, as in this video, but even so, in this type of low light, is it possible to have it not occur? Maybe specific exposure settings or something? Its not as noticable in the wmv, but uncompressed it looks like your peering through a peroscope, its VERY dark around the edges. This was also filmed with the hood removed, so it doesn`t seem to be the hood causing any of it.
