I find black bars on the left and right of the screen far more annoying than a stretched image. In fact I can't even bear to watch anything that has black bars on the sides. Black bars on top and bottom I don't mind. I think it is because that is how basically all dvd and hi def movies I have seen are (aint it nice if hollywood that when all tv manufacturers switched to wide screen they decided to only film in ultra wide screen so you still get black bars).
