Here is the situation.
I have the Batman Beyond:Return of the Joker dvd.
On my 16X9 tv, the dvd picture is shown in a rectangle
with a black border on 4 sides.
The movie seems to be in a widescreen format, but Warner Bros. chose
not to do an anamorphic 16x9 dvd.
Is it possible to re-author this movie in an anamorphic 16x9 dvd?

Thanks in advance,
R.
