I just finished shooting a feature with the DVX 100A and it looks great! I agree that it takes knowledge and experience in cinematography to achieve a “film look” with a dv camera. Some things that will help are:
-getting a shallower depth of field (there are several techniques to achieve this)
-use softer light sources
-I used the recommended settings from the Shooting Digital book from DVFilm (dvfilm.com)
-put the camera on a tripod or somekind of support (handheld on a dv camera is a dead give away that its dv)
-study other dv films

Unfortunatley there is no magic switch on the camera to get great results immediately.
