Hi Grubert.

This is not what the OP is asking. What he's referring to are discs (from what we've found so far, primarily DVDs) that are listed as 1.85:1 on the case but do not have the tiny black bars on top and bottom. We've been trying to figure out why. As far as we can tell, the reasons could be one of the following:

• Case is wrong and the DVD is actually 16x9 (1.78:1 NOT 1.85:1)
• DVD is anamorphic and might be stretched to fill the screen
• Display might be forcing some overscan

Are there any other possibilities we've missed?
