Standalone DVD players seem to allow for this delay, but software DVD players don't. I've verified this by videoing the screen of my laptop and of my TV, both playing Star Wars, then looking at the waveforms of the captured audeo. With my standalone player and TV, the music began in the same frame as the words STAR WARS first appear, but on the laptop the sound started first.
What first tipped me off was watching my first test burns of my SE LD->DVD edit and noticing out-of-sync dialogue.
