I've both Sony DVP-NS76H & Philips DVP5965K/98. Using HDMI on the same display, I found the DVP-NS76H produces more natural colours compared to the philips. Also on relatively fast motions, the sony player showed smoother pictures, compared to the philips which kinda judders a bit.

Sound wise, I prefer the sony player as well. Somehow its sound has more punch, especially on both the surround satellites.

Sensitivity wise, the philips player plays basically everything. Not fussy at all. I had a couple of DVDs which skips a little on the sony, but no problem playing the rest.
