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? > Selva's point is that "720x540" is a 4:3 frame using 1:1 pixels, but, > "720x480" is *not* a 4:3 frame using NTSC pixels. Oh, ok - but that was already known ;) > The difference between 9:10 and 10:11 is 1 percent -- I doubt that anyone's... 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. > Hmm... it is, of course, completely possible that the people who wrote the > standard for "DVD" decided that everything was referenced to some mythical > "720x534" frame size.... :^P 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 ------------------------------------------------------- This SF.NET email is sponsored by: eBay Great deals on office technology -- on eBay now!
