any help would be appreciated.i just installed two comcast dta boxes and i’m having problems using closed captions.when i turn on closed captions via original tv remotes on each of my tvs, the captioned words are spelled incorrectly due to multiple letters appearing on screen.for example, the word “effective” is spelled, effectivvev. the word “tank” is spelled tantkks.this happens on both tvs. one is an olivea 532h lcd hdtv and the other tv is a small toshiba 12″ tv.i called up comcast and the techs had no answers for me.does anybody have any ideas on what’s going on? thanks.
