Video is now finished! At least, it's as finished as possible. I'm going to render it out and watch it with my roommate tonight or tomorrow. If I notice any technical issues that hinder my or my roommate's enjoyment of the movie (she's never seen it, so she might be the better judge in this case), I'll go back and fix them before rendering out the final version and uploading it.

While this was a pain in the ass, it definitely wasn't as bad as I was expecting it to be. I'm quite pleased with the result, and it's wonderful to hear Paul McGann's voice at the right pitch in the movie after hearing it that way in the audio dramas.

--edit--

Sooo...does anyone know how to convert chapter times and subtitles from PAL to NTSC? Preferably on a Mac, as I plan to use DVD Studio Pro to author the disc.
