I tested some more. Stretch has some effect, perhaps something has changed and I don't know how to set it.
If watching an old tv show, lets say one encoded at 480x480, With no changes set in options, the video plays in a small window surrounded by black bars on all sides. If I Press A until it says "stretch", it stretches the video up until it hits the top and bottom and stops, with black bars on the side, in other words the aspect ratio stays the same, the picture just gets bigger. I want it to fill all sides of the screen (Plasma Burnin is one reason), and I can't make it do it anymore. I have chosen Video Advanced 1:33 -> 1:78 and all the others. I can't get it to fill the screen anymore. No combination of stretch and aspect changes makes a "square" picture fit a "rectangle" TV. In 17 you set both stretch and 1.33->1:78 and every video perfectly filled the screen with nothing cut off.
How do I do that in 18?
Thanks
Don
