Using the subtitles button on the DVD player in the living room (my roommate's older Sony), it came up that there were two subtitle tracks, and I could toggle through them via the remote as the scene played, but only the regular dialogue appeared for the first track and there was nothing in the second track. Confused the hell out of me, as I've never had problems with his DVD player before -- we use it all the time when we watch movies together. Once I got an email about this problem, I put it into the DVD player in my room (a newer Sony) to check it out again and it was fine. Quite odd, to be sure. So I checked it again in his and once again, I saw nothing. Not a thing in the alternate sub track. Definitely some weirdness going on there, but it appears to be limited to his player.

Sorry for the false alarm. I guess I should have checked into it further before saying anything. Still, color me as one very confused Demon Hunter today.
