Unless the scene is different to the DVD extras it will only give you the Sebulba shot in potentially better quality than on the DVD (and it's probably the same quality) - the crowd shot isn't in it.

schorman- You can use WM Capture to capture it in "perfect quality" (noting it's a capture tool not a DRM stripper), or if you have the iTunes version you can use one of the available DRM strippers (eg. Requiem, TunesKit, NoteBurner, or M4VGear). There's no DRM stripper for Amazon Instant Video or the others that use Silverlight, except perhaps for Aimersoft DRM, but it's unclear whether that program is genuine or not (you could try the trial and see if it is a DRM stripper or simply using screen capture to "strip" the DRM).
