I don't know if this has already been fixed, but I thought about the first line in the English SDH subs for SW being "Did you hear that?", but no line before it telling what sound it was. (The alarm, explosion?)
If you're talking about just scaling the existing DVD subtitle graphics, that's something You_Too may be doing for the Blu v2 project (not sure).
Actually, I OCR'd the additional subs and they'll be re-rendered in high quality.
