one doubt friends.. How we are telling it is in 16:9 ratio.. Actually by seeing the channel i am able to realize that there is some change.. the pictures not widened now but is there any other way to actually confirm whether its in 16:9 ratio. Why i am asking is if i go to aspect ratio settings and select the option of not stretching the video if its an 4:3 signal, i could still see the black pillar box on both sides of the video.. so does it mean its still 4:3 signal???????? i hope you got my doubt.....
