First of all, who says it's HDTV problem? Second, I am talking about component/HDMI cable that be using between HDTV/360/Bluray/HDDVD/HD digital cable with DIGITAL CC. It works on my brand new sony 60inch HDTV but it won't work on my dell 24inch HDTV and samsung 23inch HDTV.
P.S. who gives a fuck about non-progessive scan and progessive scan. No one wants to watch 480i or 480p, damn. I rather to watch either 1080i and 1080p formats.
Neither HD DVD and Blu-ray use closed captioning in most cases. They replaced it with SDH. However, Fox does list the CC symbol on their Blu-ray covers, so maybe that one will take advantage of the advanced mode of CC.
