Umm, this might be nit-picky, but it's not entirely accurate to say that component video doesn't support sending closed captioning data. If it's progressive scan (e.g. 480p), Devin is correct. But if it's interlaced, (e.g. 480i), then CC data CAN be sent. That's why I'm not giving up my DVD player and it's component out and why I switch back & forth between 480p and 480i output, depending on whether a DVD has subtitles or CCs.
