What's the difference between the FULL mode it has and the "fill out" you want to have? That isn't really clear from your post.
My new Lcd TV 32LF561v doesn't let me change the aspect ratio while in USB mode..I tried going to antenna and changing the aspect ratio to suite that resolution but once I flipped back to USB mode again it didn't change anything.
SO my question is.. How do I fill the picture out on my screen in USB movie mode??
The only function available in USB movie mode is changing it from FULL to ORIGINAL and thats totally useless because it just shrinks the picture down into the centre of the screen.
