Added HDMI cable, lost closed caption
Added HDMI cable from cable box to HD Plasma tv. Picture and sound improved considerably, but lost closed caption on all channels. Used 4' Rocketfish cable from Best Buy. After captioning was lost, tried another of the same cable, still nothing. Tried multiple tv HDMI imput ports, same result. When viewed through a standard coaxial cable captioning works. Is there a problem with closed captioning through HDMI cables?
