It DID install on your SATA drive, but you got a black screen? If it's booting to the Apple logo, you're getting the spinny thing (or scrolling text in -v), then it suddenly goes black, it's more likely a graphics card issue. -x should resolve it, but then again, there's times when that didn't work for me, either, and it was still a video problem.
Retry iPC on the SATA drive, but this time, make a point of installing NO video kexts. Uncheck any and all graphics related kexts in the "Customize" page, otherwise select whatever you did last time, and give it another try at installing.
True, this is going to most likely mean no QE/CI, but that can be resolved after you're sure everything else works as opposed to getting slapped in the face with a black screen at boot.

(And no, I didn't inject anything into my DVDs.)
