Actually, a good camera on full AUTO would never have created this problem unless it was defective, or the lighting was a lot darker than it appears. On AUTO, most cameras will seek an average setting combination, something that will work well most of the time, for example: f5.6, ISO 400, .125sec. Only when operators begin to drastically alter the basic combination do problems of this sort arise. I think it is great when an operator (photographer) wants to experiment with manual adjustments, but I recommend a quick photo in AUTO to set a basic benchmark, then followup photos in manual if desired. If the manual shots are better than AUTO, great, if not, the AUTO shot will probably tell you why, and provide an insurance (usable, but maybe not perfect) backup

A good camera in manual will allow you to play with the light in a way you cant in auto... You can set the scene to your style or preference in a way that cannot be replicated by Auto settings.
As a D5100 owner soon to be D600 or D800 because of all the issues (back focus & Oil spots at small apertures F22 and above) that the D5100 comes with I too had the same problem that Auto shots seemed grainy until I started to manually set my ISO - Aperture - Shutter speed since then the pictures I have taken have improved 100% from auto settings and it is becoming instinctive to change one then balance the other for the varying effects (auto Scene settings) if I have a problem simply sit back and think it through.
