Think of it this way. Rather than having a cheap bootleg internet copy they HAND-delivered a professional DVD copy for her to watch.
I give them kudos for personal attention they gave her wish.
It's one thing to redirect someone to a web page, it's much more personal to deliver it to their hands by a guy flying cross country.
I agree with you that sending the DVD copy is better than a poor quality online version, but time was the issue here-she was going to die at any moment and it was her last wish. She was desperate to see the movie, not desperate to have dolby surround sound.
