Awhile back I came across a website that had a TV show from the late '50s called "The Silent Service" for sale on dvd. This show was about the US Submarines in the Pacific. I remember watching this series late at night with my dad when I was a kid (seems like a long time ago). Would anyone know where I might be able to buy this series. I remember it being available on dvd but cannot remember where , nor can searching the web bring up any clues.
