I don't know the exact Philips player, but chances are that it contains second
generation Philips chips, as do lots of other non-Philips players, with the
notable exception of Japanese players.  Anyone who wants a standard digital
audio output from any such player has a fairly simple task:  Find the SAA7220
chip and.., well that's it really, as the chip has a digital audio output
provided.  You need to provide a rear panel socket, a capacitor and two
resistors.

Details like pin number and values are to be found in the full Philips
datasheet for the SAA7220, which I don't presently have to hand, but is freely
available. 

Hope this helps, and is of general interest.

Cheers,
Steve.
