Yup... all the RX-V series are reassignable (I own a V540) my original DVD player (Toshiba SD-1800) only had a SPDIF out (coaxial digital) and the Yammy only has a SPDIF in labelled for CD, really easy to reassign - if you need help, let me know.
BTW, as an aside - all Yamaha's CD-Ps have Toslinks only I'm told, so why they'd label it for a connection their own product line doesn't have, I don't know.
And yes, since your next question will be "but does the SPDIF labelled CD-P carry 5.1 bitstreams, not just stereo?" the answer is yes.
