Well, apparently if you have a TV from this decade, you should be able to fiddle with the ratio to get it to look right anyway. Unfortunately, all my TVs are still ancient fullscreen SDTVs that I'm praying will go out sometime soon so I'll have a reason to buy a widescreen HDTV (as far as my wife is concerned).
The good news here is that the ISO was free because of my VOD purchase (I assume) and Piobman had the fix before I burned the disc, so I'm happy with my non-purchase/gimme.
