High Definition Video on the PC

Tom's Hardware Guide:

We'll concentrate on high-definition video formats like HD DVD and Blu-ray, and dig into what it takes to get them to work on the PC and investigate how the user experience is impacted by the new HD digital rights management components.

With this eye to the future, we'll use the newest video card architectures available, as well. We'll see what Nvidia's newest DirectX 10 cards, the Geforce 8800, 8600, and 8500 can do for HD video. We'll also see what ATI's newest flagship card brings to the table, the HD 2900 XT.

It's a very thorough and informative piece.
