1) DoReMi Labs has an FCP plugin for $1000 that does unencrypted DCP authoring.
2) DigitAll in australia has a PC based player that plays unencrypted DCP SMPTE and Interop for $250
Fraunhofer has a great package that is an amazing deal for the money. It is modular, if you get all the bells and whistles it's about 10-12k... but you can get a basic setup fo unencrypted for about 4k. Really great software. It is as good or better then the "really high end" stuff. I've used them all and the Fraunhofer is my favorite.
But the DoReMi + DigitalAll is the cheap and easy way to go.
