Actually, I think you are be right about the aspect. I seem to remember having the same issue after converting it to a 2.35:1 aspect after capturing my own PAL set a while back, despite the sleeve stating its at 2.35:1! Even with the black bars uncropped (left and right only) that are normally overscanned by CRT TV's, its only in the region of 2.3:1.

I don't understand how SET is anamorphically encoded though, as stated in your description of the source materials for the comparison, as it has been upscaled to 1280x720 (which isn't anamorphic) from a letterboxed source (also not anamorphic).

No seeders on the torrent ATM, I'm going to leave my system on once its complete and help to seed it, although that could be a while as its currently only 0.1% complete. ;)
