What play mode do you all use for movies and TV being delivered in stereo (2-channel)? For instance, say there is a good movie on TNT that you want to watch, not being delivered in any of the real surround formats. So, what do you use? Prologic? Prologic II? DTS:NEO 6? a DSP mode? plain old stereo? I have the Onkyo TX-SR600. Using prologic II I find that almost everything, if not everything comes out of the center channel. I seem to get better results with DTS:NEO 6 and the TV DSP mode.
