Video reverts to 4:3 when playing

[dragonsfire]

A few days ago I pressed some keys accidentally fumbling around and now whenever i play a vid or double click to enlarge the screen it pops into 4:3 instead of 16:9, even in a play list as it goes to the next show it pops back into 4:3.

Using 1.22

Thanks!
