If you have the same problem in ubuntu and w7, the proble isn't the codec. See the top-left corner of image. There aren't shadow.
Maybe low resolution in original video.
Best regards.

Well if the video is slow the quality of picture is perfect! But if it is little fast you can notice the shadow .
that;s why the logo quality is very good !!
