Funny squeaky voices

I burned 3 movies into a dvd r and when I play it on my dvd player, one of the movies has funny squeaky voices All other movies sounds fine but this movie in particular has funny squeaky voices. The background music is fine but the voices is very weird. The voice sounds fine when played on my computer. Is there something wrong with my dvd player that it won’t play this particular movie well or something?

Any insights would be great. Thx
