Also, the Oppo has an LPCM output of 48K, 96K and 192K, simultaneous (if I am interpreting the manual correctly - I don't use HDMI audio) digital audio output to HDMI, Coax and Optical, which the Philips does not, a nice remote, and a signal to noise spec of >100dB.
Interesting comments, lets see how the Sony DVP-NS77H does compare in those aspects. Mind you in most situations the average user doesn't get this technical. ;-)
Adjusting Gamma - Sony doesn't have a feature exactly name that, but as a few preset settings under custom picture mode (page 36) and memory choice allows adjustments to brightness, color, and hue to your tastes.
Colorspace for HDMI - under screen setup you have a YCbCr/RGB(HDMI) settings (page 58) that you can toggle either YCbCr or RGB. Note if HDMI out is connected to a DVI your stuck with RGB.
LPCM output of 48K, 96K and 192K, simultaneous - Digital out (page 61) says digital output will occur via HDMI, and optical/coax simutaneously, or you can turn it off, and get PCM only 48k, 96k.
Audio specs - Sony decided to not list all the usual things, but previously Sony had the following Audio spec for the DVP-NS75H:
Signal-to-noise ratio (S/N ratio) 115 dB
Harmonic distorion: 0.003 %
Dynamic range: DVD Video: 103 dB/ CD: 99 dB
DVP-NS77H has none of those spec's listed?
