If I watch a DVD on a "wide screen" t.v. , would the black bars not show automatically since they t.v. can now show the movie in the proper aspect ratio?<P>How much wide than it is tall does a t.v.

If I understand what you're looking to do, if you uncheck 'Displays have separate Spaces' in Mission Control, that should do it. That's already off. I can have windows spanned across multiple screens ...
