        That might be - and I thought he was making it up but I wonder where
        Adobe came up with the idea.   Is there a conspiracy to confuse folks
        going on?

        Oh, ok - but that was already known ;)

        Or ~6 pixels over the height of the screen.  Enough to cause overlays 
        to not coincide with the menus - which is what the documentation was 
        talking about.

        In broadcast TV studios there is a 720x486 size used.   One of my 
        brothers (who does know about this - perhaps I should ask him what
        is going on) corrected me with 720x486 when I mentioned 720x480.   
        Perhaps the DVD folks had that in mind.

        I'll find out the hardway soon enough - but with a -RW disc of course ;)

        Cheers,
        Steven Schultz
