HDCP may be necessary to play your high definition DVDs at their full resolution, and even though ATI listed it as a feature on their website, the cards did not actually support it. No surprise that a lawsuit has now been filed by some disgruntled consumers.
We're no legal experts, but having a feature on the box and not actually being able to use it in any circumstance is leading us to believe ATI may just have to take an L on this one. As it stands only a few PC videocards actually do support HDCP, and they are NVIDIAs packaged in Sony Vaios. Although ATI has an HDCP-compatible card in development, none have hit shelves yet.
