There are some channels that broadcast in 4:3 with 16:9 content. When I see these channels in Windows 7 Media Center is a mess becouse I have to costantly change between zoom1 (standard channels in 16:9) and zoom2 (channels in 4:3 retrasmitting on sat 16:9 contents). There is a way to associate zoom to specific channels or use a special zoom like some (cheap) LG tv that made width automatic adaptation preserving aspect ratio? thanks!
