DVD on a USB stick

I copied a DVD movie to a usb stick instead of burning it to disc to watch it.
It is a full length movie ripped from a legit disc.
The burned copy shows ok as usual a full wide screen 16:9.
The copy on the usb stick plays but only shows in 4:3 format.
I have played with the tv screen settings but i can't get it any bigger.
Any ideas.?

I'm guessing your trying the usb input on your TV ? Check the TV's input source settings, it may be set or limited to 4:3 aspect.

USB on tv yes.
I can set the tv to 4:3, 16:9 or movie or any other steeing and it makes no difference. The movie on the usb is a square 4:3
