why does having an hd box (DCX-3200-M) lowers the resolution of non hd channels. the resolution is alot better without the hd box. and change it to 4:3 screen. even when settings is change. shaw should fix this. cause i think no one watches 4:3 anymore. kinda defeats having a wide screen. does anyone here know how to fix this or get rid-off 4:3 at least?
