DNG is raw. Red tint in whatever app, Mlv App or acr for instance has all to do with color matrices, white balance and so on. Or maybe white level is strange, or the preset you use. Who knows.
If something is odd with the dng files when comparing Mlvfs or Mlv App you could show us your examples here. Also post your example dng files. The more specific and the more visual information you provide, the faster you´ll get correct solutions and answers.
