i hope somebody can help me here,

when i used to have my dvd players , some dvd's that weren't shot in hd i get bars on the left & side on the screen but i can easily get rid of those bars when i edit my tv settings on my dvd and choose 4:3 letterbox then i have the full image in the screen without those bars.

now i got a blue ray player , so i played a blue ray that isn't shot in hd & like usual i got those bars on left & right , but the problem when i edited my settings to 4:3 letterbox i still couldn't get the full image on the screen & get rid of the bars !

is there any way to make my blue ray operates like my dvd player & get rid of those bars when they occur ?

there is a reason why there are black bars. in order to keep the correct aspect ration that the film was shot in, the black bars will appear.
it does not matter what format something is in if the movie was shot in a specific aspect, you will see black bars unfortunately.
