It can't be done without cropping-- a 5x7 will always have a different aspect ratio than a 20x30 image. If you don't crop and want to "grow" the 5" side to 20" the 7" side will end up 28" long, or, conversely, if you want to make the 7" side 30" long the 5" dimension will need to be 21.4".

This is why a 35mm negative will always have some image content missing when it is printed on 3.5 x 5; in order to preserve all of the scene it must be printed to 4x6 to preserve the aspect ratio (2x3) because the 35mm negative is 24mm x 36mm-- a 2x3 aspect.

In photoshop or a imaging software, you open the picture, and go to image size, then chose your target size with the "preserve scale" option

Plasma TV color problem

Sometimes, poor picture quality occurs when having activated an A-VHS camera or camcorder connected and having connected another peripheral at the same time. In this case switch off one of the other peripherals. Also, The norcent has a known problem with progressive scan - when connected to a progressive scan source, it yields a distorted screen with dual images and messed up colors.
