I am having a problem when authoring with Encore CS3 on an Intel Mac.
I have compressed a 16x9 SD movie in Sorenson Squeeze. I bring it into Encore for authoring.
When I preveiw the disc before building, with the preview set to show 16x9 letterbox in a 4x3 frame, I see a thin white line at the bottom of the letterboxed image. If I burn the disc, the white line is also there. See attached jpg (levels adjusted for clarity
When looking at the asset in menus where the images is not letterboxed, there is no white line at the bottom of the image.
If I author the same material in DVD Studio Pro, I do not get this artifact.
