I just hooked up my Time Warner digital cable HD box to my widescreen hdtv and I'm having trouble getting rid of the black bars on the side. Since I'm using one of the HD inputs on my TV, the TV manual says I have to use the input device to change the picture format (ie. Widescreen, zoom, stretch, etc.), Well, the box doesn't have that capability, according to the tech support at TW. Should I just connect the box to one of the normal inputs so I can lose the black bars or what. Is the one HD channel, HBOHD, worth risking burn in on my brand new HDTV? thanks for your input.
