The reason is that the director of the film (Into the Void) has said that he would prefer for viewers to see his film at 25fps instead of 24, but all Blu-Ray releases are at 23.976. I haven't seen the film, but I would like to, and I'd like to see it the way the director intended for me to see it. That, and it makes the movie about 6-8 minutes shorter, and from what I hear of this movie, it's already too long.

Plus it gives me an excuse to test out my roommate's projector's capabilities, which can apparently display NTSC or PAL at the intended framerate.

I'll try out your method, but I'd really like to keep the DTS encoding if at all possible.
