I bought the movie "Darkness". I wanted Full screen but it was widescreen, so I bought another one that was "FS", but it's the same as the last, WS. They both have the black boxes on the top and bottom of the screen. Why does it say it's full screen? And is there a full screen version or would I just have to wait until they play it on tv?

I don't see any setting on the DVD for that
Neither does my tv have any settings.

The DVDs are one-sided. One is red on the cover and the disk is also.(widescreen)

The other is a blue cover and blue disk (says it's full screen on back but is still widescreen.

Why is that?
