what do you mean with "support Blu-ray"?
I'm using a Core i3-540 and HD Graphics on a DH55TC via DVI on a 22" HP: Blu-ray Discs are playing fine with the bundled PowerDVD 9 of my Samsung drive. Expect when I'm activating "Intel Clear Video" in PowerDVD the picture is not ok. But when playing BD without this, I have a CPU utilization of around 20-30%. So Blu-ray is no problem at all.
