Just hooked up a Pioneer 4330 plasma to my digital hi-def cable box (Rogers Cable in Toronto). When I choose the component input on the TV, which provides a 1080i signal, I can watch hi-def channels in widescreen. But the rest of the channels are shown in 4:3, and the TV won't allow me to choose widescreen mode for these channels. If I switch to the S-video input, the widescreen option for 4:3 content is now available, but I can't display the hi-def channels. I have scoured the manual and tried every option but it seems I'm sunk. I guess I can do a macro button to switch inputs for hi-def, but this gets in the way if you like to channel-surf like I do. Anyone have any other ideas?
