Not sure what good it'll do, but here's the log file, below. I think the subtitle track must be some weird non-standard format. Even the full DVD rip will only display the subtitles in VLC. Boxee sees a track, but then nothing displays when that "subtitle English" track is selected. Very strange--and annoying.
