Seriously, folks -- DVD Decrypter is FREE!!!! Go here, and ignore the Nero part (it has ImgTool and DVD Decrypter downloads); it's a guide on how to make a DVD from AUDIO_TS and VIDEO_TS (and i STRONGLY reccomend adding an EMPTY AUDIO_TS folder next to the VIDEO_TS folder if there isn't one BEFORE you make the ISO, for better compatibility with older players, and just to be safe put it in front of the VIDEO_TS because I really don't know if that makes a difference but I've always seen the EMPTY audio folder come before the video folder). That's the same way I did it and all three anamorphic discs work flawlessly.

--EDIT--

Actually reading the tutorial it seems the AUDIO_TS folder is created for you, so ignore that part.
