You see, the DVD player uses an HDMI output, which uses HDCP copy protection. The video unit uses DVI. No copy protection.
Copy protection was implemented so that content providers and hardware manufactures could offer me a far better video experience than I could get over analog composite cable. So far, I'm digging this user experience.
So I guess I'll run over to Good Will, which has a bunch of old tube TVs for $20.
The whole experience, quite frankly, has put me right off all the "content" that I can't see. Maybe I won't bother replacing the TV. Screw 'em.
