I was correct, RE: Component outputs - from the Oppo site:
I don't know if this is true of all upsampling DVD players (anyone?). If you are limited to 480i/p I don't imagine you'll see the kind of improvement I've experienced via the HDMI output.
Component video output with progressive scan (Up-converting over component output is only available for unencrypted DVD discs such as home video and consumer-created contents. Most commercially pressed DVD discs are CSS-encrypted and will be limited to 480i/480p output over component. HDMI output is protected with HDCP and has no such restriction.)
