Does anyone here have experience with Blu-ray on the PC? What are some of the better options for (1) drives, (2) software (e.g. PowerDVD Ultra), and (3) sound cards?

As I haven't done any research, I'm also wondering if current hardware and software programs support uncompressed PCM output to S/PDIF or HDMI (or to firewire-based sound cards). What are the associated DRM issues?
