Not all TVs that take component ins actually do anything serious with them. It has to be more than a standard TV to accept a progressive scan signal. You might spend a bundle on component cables and be no better off than with a mediocre s video cable. Depends on the TV and the DVD both!

I recently hooked up a Toshiba DVD to a LG plasma with component in progressive mode and the pic was quite dark. The S-video input looked better. Even the component in with interlaced scanning looked better than the progressive scan. That's where I finally left it, since I needed to run all the component ins through the A/V receiver.
