Shrink to Fit DVD Player for old 3:4 movies?



I read somewhere (I think it may even have been in a Club MyCE forum) that there are DVD players that have the option to “shrink” a “full screen” image so that the edges of the picture aren’t cropped as always happens with old movies shown on TVs and Monitors.

I’ve tried Googling to find a player that will do that, but I keep getting hits for the DVD Shrink software.

I’d be grateful for some help finding a player that will display the full frame image of old 3:4 aspect ratio films.
