^But an LD image isn't quite as clear, so you wouldn't see the aliasing as much thanks to it being a bit blurry. Also, if there really is a vertical blur, does that mean that the release was modified and not sent out just as-is straight rip? Interesting... shame they couldn't have been assed to do any more.

If you check the end of the X0 Project thread, there are some screenshot samples addressing this. You can see the detail loss from the vertical blur on some of Artoo's finer details.
