Query: Poor Sound & No Closed Captions or Subtitles

We gave this a good try. Watched the first episode twice and the second episode once. The sound quality just does not make it. We miss 15 to 20 percent of the dialog. It's a shame because this looks like a really good series. Poor sound quality seems to be a consistent problem with BBC productions. With the poor sound quality we really need the Closed Captioning or Subtitles. I have tried every setting on the Sony DVD player that I can find, but no Closed Captioning or subtitles. The box indicates that it has Closed Captioning, but I can't get it to work. Too bad!
