Only full screen when using HP DVD?



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???


also when I tried to fit an avi file onto one single sided dvd it would be over the limit. I changed the setting to auto fit and it only burned half way through the video. anyone that uses this program?
