Which of my two ancient DVD players is better?

[markusg]

Sony DVP-NS400D
Toshiba SD-K600

I know the Toshiba is 24 bit 192khz Audio DAC.
But the Sony doesnt mention anything like that in the manual.

Is either picture quality better than the other? How do I determine the chips inside, which isnt listed in the manual.

found this on the Sony:

DAC:
96kHz/24 bit audio DAC
27Mhz/10 bit video DAC

since 192Khz/24 bit is way better than 96khz/24 bit, I guess the Toshiba wins.
