There are no black borders (beyond the few lines in Moth3r's original). You have the full 360 lines of picture that all other anamorphic transfers will have.
It looks pretty darn good.

You're right. It does look pretty darn good.

Going back to what I said before though (and this is more of an FYI thing), your video resolution doesn't have to be 360 lines. Most of the other anamorphic transfers have more than that. The official DVD, for example, has a 720x365 viewable area. To keep the same aspect ratio you have in your screenshots, you could easily resize your video to 720x368 instead of 704x360. This would not only result in a little bit less quality loss from Moth3r's 432-line original, but would completely eliminate the side borders altogether. Just a thought...
