Playing Back 16:9 & 4:3 Correctly

[Damage Inc.]

Hey everyone,

I've been trying to get this TV to display both 16:9 and 4:3 correctly under 1 setting.
It does put the digital TV content in the right aspect ratio, like not stretching 4:3 into 16:9 and all.
However, for the BD-player and the PS3 connected, it simply stretches any 4:3-content.
Is there any way I can fix this or will I have to keep switching at every change of aspect-ratio?

Also, without changing the settings, any 4:3-DVD is displayed correctly.
However, try a BD such as 'The Matrix', playback the bonus-content and it's stretched.
(I'm not sure if it's with all of them, but the bunch I tried this is the case.)
Which is just very weird, confusing and annoying...
