Whenever I burn an avi file that should be widescreen comes out as full screen and stetches the picture up and down. If I change my tv that is not a widescreen tv to the widescreen setting it looks fine. My other tv dose that have the option of this is it doesnt look as good. Im using the software (HP DVD) that comes with the external HP DVD640. Is there anything I can do to make it burn in widescreen???
