White Border Around Photoshop image when I export from FCP 6

I have an image of a logo that I created in Photoshop. I imported it into FCP 6 and layed it over my video. When I play the sequence it looks perfect. When I go to export, a thin white line suddenly appears around my photoshop image. It appears in FCP while the export is happening, and I see it in the video file I created. I do not see the white line while editing or playing the sequence. I'm not sure what is causing this....please help!!!
