dont think it would be as it is my niece's wedding from last year. She sent the DVDs it was for sister but she doesn't have a DVD player nor does she want one.
I don't know anyone that would do. You need to take your dvd player to your sisters, connect it up and record it on her video player. That's the cheapest and easiest way.
Of no help whatsoever but I have only recently got rid of a machine which converts between VHS tapes, DVD or the machine's own hard drive (any one to any other). It was very useful when I was converting all my VHS tapes to DVD but I don't use even those any more.
