Yes, but Neil was talking about encoding a file for the web, not for
creating DVDs or watching the files on a giant screen.

Yes, I know. But G3 and G4 computers are specifically mentioned as not
capable of playing back HD trailers, so there's no argument there. Neil was
talking about how G3 and G4 computers can't play back H.264 encoded movies
very well, and that's not true, at least for my G4.
