1. The drive.
2. The player. Try http://www.cyberlink.com/multi/products/main_112_ENU.html which writes "Watch new high-def movies on HD DVDs or Blu-ray Discs"
Seems easy enough.
So I'm still not sure about what I need to play HD discs on my PC. I have an HDCP-enabled (or is the term "compliant"?) display but it has only DVI-in, not HDMI-in. If I were to get say that new Sony SATA internal Blu-ray BD-ROM drive, could I play Blu-ray discs to my display or not?
