also I have another question. when i look at standard format channels I get a full screen on my PN50A450 but when I look at HD channels I get the black bars at the top and bottom of screen. It should not be like that correct??? I went into menu on tv and I have 16:9 format set. I also have 16:9 format set on my comcast cable box and I also played with settings on cbl box and changed resolution from 720p to 1080i and that still didnt chg anything. can someone help please?? also if I remember correctly I could access JUST SCAN feature on picture menu screen and that seemed to adjust picture fine BEFORE i hooked up cable box but now since I have box connceted JUST SCAN is greyed out so
I have a HDMI cbl going from hm theater to tv and also a HDMI cbl going from cbl box to tv....now regarding the optical cable, is it best to go from the cable box to the tv OR from the home theater to the tv OR from the theater to the cbl box? I think either way will work but what is the difference?
