I see no difference.
On a related subject, I remember we went to see an English movie last year... think it might have been the new Harry Potter. Anyway, it had English subtitles - and this douchebag sat in front of us started kicking off and complaining that it was distracting him. I was with my brother & niece so was getting a bit pissed off because he was distracting everyone else: I didn't see any difference. Thankfully he stormed out before I slapped his face and his ass.
Turns out they were on because there were some deaf people in the audience.
