Cannot get full screen picture. seems like I still have a 36 inch tv.
It is a 42 inch LG plasma hdtv
It seems like you're expecting a 16:9 ratio picture. If you're sending a 4:3 ratio signal to the TV, you'll get a 4:3 ratio picture. An option would be to use the remote and set the TV to a 16:9 ratio picture, but that'll stretch the picture and make everything look fat. Another option would be to use the remote and zoom in, but that'll chop off the top/bottom of the picture a bit. Either case would be annoying. Some make matters even more annoying, some programs are broadcasted in a 16:9 ratio signal, but the actual picture is really 4:3 ratio. So...... as long as the pictures don't look skinny, fat, or chopped off, just accept it. If you're really that picky, just watch new Blu Ray movies only.
