Distinctly non-trivial. The receiver software is cryptographically signed and is heavily integrated with the conditional access system securing the underlying broadcast. I'm only aware of one time that a legitimate box was encouraged to run a lightly-patched version of the software, and that involved a JTAG-type attack on a specific model of set top box. I believe that lesson has been learned in current models.
