It can take a long time for shows to come out on DVD. I'm a huge Forever Knight fan as well, and that show is finally coming out on DVD in October this year (thanks in no small part to writing campaigns by the fans). I'm sure L&C will be on DVD soon. It just takes time.

I believe there's a hero in all of us that keeps us honest, gives us strength, makes us noble, and finally allows us to die with pride, even though sometimes we have to be steady and give up the thing we want the most. Even our dreams. -- Aunt May, Spider-Man 2
