ProfessorStein said:Yeah, preview quality. If you're getting 640x480 at all, you're already doing better than I am with my RE500. I don't think you'll get better range if you set it lower, if that's what you're asking. It's just the only way I can have a preview that isn't continuously freezing/dropping frames. I have to run 320x240 @ 15 fps. (though, just because you have it set to 640x480 doesn't necessaily mean that's what you're actually getting)
